Given numbers are 641,473,553,160,474

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

The LCM of 641,473,553,160,474 is 80479549920.

Find LCM of 641,473,553,160,474 with Prime Factorization

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

2 x 79 x 641 x 473 x 7 x 80 x 3 = 80479549920

Therefore, the lowest common multiple of 641,473,553,160,474 is 80479549920.

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.

641 x 473 x 553 x 160 x 474 = 12715768887360

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.

641 : 1, 641

473 : 1, 11, 43, 473

553 : 1, 7, 79, 553

160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160

474 : 1, 2, 3, 6, 79, 158, 237, 474

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,473,553,160,474, is 1.

Now, the common factors can be found like this.

641:641

473:11x 43

553:7x 79

160:2x 2x 2x 2x 2x 5

474:2x 3x 79

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

2x 79 = 158

Therefore, the value for common factors is 158.

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 = 12715768887360/(1x158)

LCM = 12715768887360/158

LCM = 80479549920

Thus, we can understand that the LCM of 641,473,553,160,474 is 80479549920.
