Given numbers are 637,416,780,697

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

The LCM of 637,416,780,697 is 213114720.

Find LCM of 637,416,780,697 with Prime Factorization

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

2 x 2 x 13 x 49 x 8 x 15 x 697 = 213114720

Therefore, the lowest common multiple of 637,416,780,697 is 213114720.

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 416 x 780 x 697 = 144065550720

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

416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

697 : 1, 17, 41, 697

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,416,780,697, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

416:2x 2x 2x 2x 2x 13

780:2x 2x 3x 5x 13

697:17x 41

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 13x 13 = 676

Therefore, the value for common factors is 676.

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 = 144065550720/(1x676)

LCM = 144065550720/676

LCM = 213114720

Thus, we can understand that the LCM of 637,416,780,697 is 213114720.
