Given numbers are 637,469,817,126,644

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

The LCM of 637,469,817,126,644 is 28871319204.

Find LCM of 637,469,817,126,644 with Prime Factorization

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

2 x 7 x 91 x 67 x 817 x 9 x 46 = 28871319204

Therefore, the lowest common multiple of 637,469,817,126,644 is 28871319204.

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.

637 x 469 x 817 x 126 x 644 = 19805724973944

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.

637 : 1, 7, 13, 49, 91, 637

469 : 1, 7, 67, 469

817 : 1, 19, 43, 817

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,469,817,126,644, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

469:7x 67

817:19x 43

126:2x 3x 3x 7

644:2x 2x 7x 23

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

2x 7x 7x 7 = 686

Therefore, the value for common factors is 686.

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 = 19805724973944/(1x686)

LCM = 19805724973944/686

LCM = 28871319204

Thus, we can understand that the LCM of 637,469,817,126,644 is 28871319204.
