Given numbers are 432,121,607,620

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

The LCM of 432,121,607,620 is 4918011120.

Find LCM of 432,121,607,620 with Prime Factorization

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

2 x 2 x 108 x 121 x 607 x 155 = 4918011120

Therefore, the lowest common multiple of 432,121,607,620 is 4918011120.

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.

432 x 121 x 607 x 620 = 19672044480

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.

432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432

121 : 1, 11, 121

607 : 1, 607

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 432,121,607,620, is 1.

Now, the common factors can be found like this.

432:2x 2x 2x 2x 3x 3x 3

121:11x 11

607:607

620:2x 2x 5x 31

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 19672044480/(1x4)

LCM = 19672044480/4

LCM = 4918011120

Thus, we can understand that the LCM of 432,121,607,620 is 4918011120.
