Given numbers are 785,420,668,566

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

The LCM of 785,420,668,566 is 3116390340.

Find LCM of 785,420,668,566 with Prime Factorization

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

2 x 2 x 5 x 157 x 21 x 167 x 283 = 3116390340

Therefore, the lowest common multiple of 785,420,668,566 is 3116390340.

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.

785 x 420 x 668 x 566 = 124655613600

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.

785 : 1, 5, 157, 785

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

668 : 1, 2, 4, 167, 334, 668

566 : 1, 2, 283, 566

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,420,668,566, is 1.

Now, the common factors can be found like this.

785:5x 157

420:2x 2x 3x 5x 7

668:2x 2x 167

566:2x 283

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 = 124655613600/(1x40)

LCM = 124655613600/40

LCM = 3116390340

Thus, we can understand that the LCM of 785,420,668,566 is 3116390340.
