Given numbers are 302,137,640,779,420

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

The LCM of 302,137,640,779,420 is 216587925120.

Find LCM of 302,137,640,779,420 with Prime Factorization

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

2 x 2 x 5 x 151 x 137 x 32 x 779 x 21 = 216587925120

Therefore, the lowest common multiple of 302,137,640,779,420 is 216587925120.

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.

302 x 137 x 640 x 779 x 420 = 8663517004800

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.

302 : 1, 2, 151, 302

137 : 1, 137

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

779 : 1, 19, 41, 779

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 302,137,640,779,420, is 1.

Now, the common factors can be found like this.

302:2x 151

137:137

640:2x 2x 2x 2x 2x 2x 2x 5

779:19x 41

420:2x 2x 3x 5x 7

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 5 = 40

Therefore, the value for common factors is 40.

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 = 8663517004800/(1x40)

LCM = 8663517004800/40

LCM = 216587925120

Thus, we can understand that the LCM of 302,137,640,779,420 is 216587925120.
