Given numbers are 780,473,470,524

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

The LCM of 780,473,470,524 is 2271563580.

Find LCM of 780,473,470,524 with Prime Factorization

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

2 x 2 x 5 x 39 x 473 x 47 x 131 = 2271563580

Therefore, the lowest common multiple of 780,473,470,524 is 2271563580.

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.

780 x 473 x 470 x 524 = 90862543200

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.

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

473 : 1, 11, 43, 473

470 : 1, 2, 5, 10, 47, 94, 235, 470

524 : 1, 2, 4, 131, 262, 524

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,473,470,524, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

473:11x 43

470:2x 5x 47

524:2x 2x 131

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 = 90862543200/(1x40)

LCM = 90862543200/40

LCM = 2271563580

Thus, we can understand that the LCM of 780,473,470,524 is 2271563580.
