They are multiples of 60.
Two and three are relatively prime, or coprime. That means that they have no smaller number, or factor, in common. So, the multiples of both numbers are the multiples of the product of the two, or the multiples of six.
Two common multiples of 21 and 15 are 105 and 315.
All multiples of 64 are multiples of 8.
This cannot be determined because the common multiples of any two or more numbers are infinite.
They are multiples of 60.
The two common multiples of three and five are: 15 and 30 ^-^
693, 924.
The common multiples of four start with the lowest common multiple. One times four is four. From there multiply four by two to get another multiple, eight. Other common multiples include 12,16,24,36,40,44, and 48.
30
The LCM is: 30
They are: one, two, three, four!
Multiply it by two, then by three, then by four, and keep going until you have enough multiples.
4, 8, 12, 16
Two and three are relatively prime, or coprime. That means that they have no smaller number, or factor, in common. So, the multiples of both numbers are the multiples of the product of the two, or the multiples of six.
Twice and three times as much as the previous common multiple respectively
Yes.
