To find the proper factors of 870, you list all the factors of 870 (numbers that divide evenly into 870), excluding 870 itself. These factors are: 1, 2, 3, 5, 6, 10, 15, 29, 30, 43, 58, 87, 145, 174, and 290.
Any of the factors of 870 will divide into it evenly
1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, and 870. The prime factors of 870 are 2, 3, 5, and 29. The distinct prime factors of 870 are 2, 3, 5, and 29. The prime factorization of 870 is 2 x 3 x 5 x 29.
870 = 2 x 3 x 5 x 29
All multiples of 870 are divisible by 870.
Divide 870 by 1, 2, 3, 5, 6, 10, 15 and 29.
2 x 3 x 5 x 29 = 870
To calculate the LCM of two numbers you first need to work out their prime factors. In this case: 29=29 30=5x3x2 The next step would be to identify any common factors, but as there are none, we simply take all these numbers and work out the product: 29x5x3x2=870 So the LCM of 29 and 30 is 870.
