Given numbers are 780,378,534,977

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

The LCM of 780,378,534,977 is 4272870420.

Find LCM of 780,378,534,977 with Prime Factorization

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

2 x 3 x 130 x 63 x 89 x 977 = 4272870420

Therefore, the lowest common multiple of 780,378,534,977 is 4272870420.

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 378 x 534 x 977 = 153823335120

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

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

534 : 1, 2, 3, 6, 89, 178, 267, 534

977 : 1, 977

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,378,534,977, is 1.

Now, the common factors can be found like this.

780:2x 2x 3x 5x 13

378:2x 3x 3x 3x 7

534:2x 3x 89

977:977

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 3 = 36

Therefore, the value for common factors is 36.

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 = 153823335120/(1x36)

LCM = 153823335120/36

LCM = 4272870420

Thus, we can understand that the LCM of 780,378,534,977 is 4272870420.
