Given numbers are 637,984,924,238,690

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

The LCM of 637,984,924,238,690 is 13479506040.

Find LCM of 637,984,924,238,690 with Prime Factorization

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

2 x 2 x 3 x 7 x 91 x 82 x 11 x 17 x 115 = 13479506040

Therefore, the lowest common multiple of 637,984,924,238,690 is 13479506040.

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 984 x 924 x 238 x 690 = 95111394618240

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

984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984

924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924

238 : 1, 2, 7, 14, 17, 34, 119, 238

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,984,924,238,690, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

984:2x 2x 2x 3x 41

924:2x 2x 3x 7x 11

238:2x 7x 17

690:2x 3x 5x 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 2x 2x 2x 3x 3x 7x 7 = 7056

Therefore, the value for common factors is 7056.

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 = 95111394618240/(1x7056)

LCM = 95111394618240/7056

LCM = 13479506040

Thus, we can understand that the LCM of 637,984,924,238,690 is 13479506040.
