Video TranscriptFind the greatest number of 4 of 4 digits, which is exactly divisible by 4048 and 60 point well. The first thing we need to do is find the least common multiple for each 1 of these, and to do that, let's break them down into their prime numbers. I will say: 40 is 4 times, 104 is 2 times. 210 is 2 times. 548 point went to say it's 6 times 8. That will be 2 times 32 times 4 and 2 times. 2.60 is 6 times. 10 there'll be 2 times 3 and 2 times 5. So i want to say: 40 is 2 times 2 times 2 times 548 is going to be 2. I got that 2 times 3. Well, i don't have any 3 written, so i'm going to put it over here to the side and then i have 2. So we'll put it underneath this 22 underneath this 22. I need to put out to the side because i don't have any more 2 and then 60 is going to be 2. So i won put that here. 3 put that under the 32 under the 2 and 5 under the 5, so oh least, common multiple, i'm simply gonna multiply the numbers in each column, 22253 and 2. So we multiply those together. So that's gone, be 6 times. 5 is 30612240 point well. 240. Is not a 4 digit number, so i need to see how much can i i need to make this a 4 digit number. Anything i multiplied by 240 is going to be divisible by 4048 and 60 point. So if i multiply this by 10, i get 2400 point. Well, that's not going to be the largest. I can multiply this by what i can multiply that by 3. If i multiply that by 3, then we're going to have 007200 point well, can i give anything bigger? So what if i take 240 and multiply it by 40 point? Well, that would be 06. There'S 9600 point: i let's see, i think we might can get by 41 point. Let'S try it. Let'S track 4340 times 41 point there'll be 240, it's gonna be 016 and 9048 and 9 point there. You go so when i take my least common multiple and keep multiplying it till i get the biggest 4 digit number. We ended up, multiplying it. Byty 1 point.
