Given numbers are 103,154,989,440

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

The LCM of 103,154,989,440 is 313750360.

Find LCM of 103,154,989,440 with Prime Factorization

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

2 x 11 x 103 x 7 x 989 x 20 = 313750360

Therefore, the lowest common multiple of 103,154,989,440 is 313750360.

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.

103 x 154 x 989 x 440 = 6902507920

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.

103 : 1, 103

154 : 1, 2, 7, 11, 14, 22, 77, 154

989 : 1, 23, 43, 989

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 103,154,989,440, is 1.

Now, the common factors can be found like this.

103:103

154:2x 7x 11

989:23x 43

440:2x 2x 2x 5x 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 11 = 22

Therefore, the value for common factors is 22.

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 = 6902507920/(1x22)

LCM = 6902507920/22

LCM = 313750360

Thus, we can understand that the LCM of 103,154,989,440 is 313750360.
