Given numbers are 665,393,954,702,420

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

The LCM of 665,393,954,702,420 is 6482401380.

Find LCM of 665,393,954,702,420 with Prime Factorization

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

2 x 3 x 3 x 5 x 7 x 19 x 131 x 53 x 39 x 2 = 6482401380

Therefore, the lowest common multiple of 665,393,954,702,420 is 6482401380.

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.

665 x 393 x 954 x 702 x 420 = 73510431649200

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

393 : 1, 3, 131, 393

954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

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 665,393,954,702,420, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

393:3x 131

954:2x 3x 3x 53

702:2x 3x 3x 3x 13

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 3x 3x 3x 3x 5x 7 = 11340

Therefore, the value for common factors is 11340.

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 = 73510431649200/(1x11340)

LCM = 73510431649200/11340

LCM = 6482401380

Thus, we can understand that the LCM of 665,393,954,702,420 is 6482401380.
