It is infinity, but I think you mean factor, which would be 4. But for this question, it is infinity.
No, 130 is not a multiple of 4 and 4 is not a multiple of 130.
No - but 4 IS a multiple of 8 !
No. 426 is not a multiple of 4
No, 51 is not a multiple of 4.
The greatest common multiple of any set of integers is infinite.
As 100 = 4 x 25 the biggest multiple of 4 less than 100 is 4 x (25 -1) = 96
There is no multiple of 63 so large that one can't add another 63 to it. There is no biggest common multiple; it's infinite.
Infinate
There can be no such number. If a number n laid claim to being the greatest multiple of 4, then n+4 would have a better claim. And then n+4+4 = n+8 and so on, for ever.
No, 130 is not a multiple of 4 and 4 is not a multiple of 130.
The largest common multiple of 6 and 9 is an infinite amount.
Any multiple of 4 is also a multiple of 2.
Any multiple of 20 is also a multiple of 4.
176 is a multiple of 4. 176 is a multiple of 11. That makes it a common multiple of 4 and 11.
No - but 4 IS a multiple of 8 !
No. 426 is not a multiple of 4
No, 51 is not a multiple of 4.
