Given numbers are 920,639,124,968

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 920,639,124,968 is 2205137880.

Find LCM of 920,639,124,968 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 2 x 115 x 639 x 31 x 121 = 2205137880

Therefore, the lowest common multiple of 920,639,124,968 is 2205137880.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

920 x 639 x 124 x 968 = 70564412160

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920

639 : 1, 3, 9, 71, 213, 639

124 : 1, 2, 4, 31, 62, 124

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 920,639,124,968, is 1.

Now, the common factors can be found like this.

920:2x 2x 2x 5x 23

639:3x 3x 71

124:2x 2x 31

968:2x 2x 2x 11x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 2x 2 = 32

Therefore, the value for common factors is 32.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 70564412160/(1x32)

LCM = 70564412160/32

LCM = 2205137880

Thus, we can understand that the LCM of 920,639,124,968 is 2205137880.
