210, 420, 630, 840, 1050, 1260, 1470, 1680, 1890, . . . (to infinity).
210 is not a multiple of 420. 420 is a multiple of 210.
There are an infinite number of multiples of any number. A multiple of a number is the product of that number multiplied by any integer other than zero. The multiples of 210 are 210, 420, 630, 840, 1050, and continuing on to an infinite quantity of numbers that can be divided evenly by 210.
No, its multiples are 21 and 10. A prime number is a number that can only be divided by 1 and itself.
Multiples of 42"Common" requires more than one number... ...multiples of 42 are 84, 126, 168, 210, etc.But there would have to be another number in order for 42 to have a common multiple.
A multiple in math is any number that is the product of that number. For example 2, 4, 6 and 8 are multiples of 2. So the first 5 multiples of 42 are 42, 84, 126, 168 and 210.
42, 84, 126, 168, 210, 252, 294, 336, 378, . . .
There are infinitely many of them so they cannot be listed. One of their multiples is 294*252*210 = 15558480.
Common multiples include any multiple of 210.
There are an infinite number of common multiples of 21 and 15 .The smallest two of them are 105 and 210 . A couple of others are 1,890 and 453,705 .
840
Oh, dude, let me break it down for you. So, if the greatest common factor (GCF) is 7 and the least common multiple (LCM) is 210, the number pairs would be multiples of 7 that multiply to 210. So, the number pairs would be 7 and 210. That's it. Easy peasy lemon squeezy.
210, 420, 630, 840, 1050, 1260.
