The factors of 280 are 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280 For them to be common, they need to be compared to another set of factors.
The greatest common factor of 70 147 175 and 280 is 7.
The LCM is: 280
The LCM is: 280
The common factors of 280 and 8 are: 1, 2, 4, and 8
The least common multiple of 8 and 70 is 280.
The least common multiple (LCM) of two numbers is the smallest number (not zero) that is a multiple of both.Multiples of 70 are0,70,140,210,280,350.......Multiples of 280 are0,280,560,840......So the LCM of 70 and 280 is nothing but 280
280
It is: 70
