Given numbers are 439,780,397,902

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

The LCM of 439,780,397,902 is 61309273740.

Find LCM of 439,780,397,902 with Prime Factorization

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

2 x 439 x 390 x 397 x 451 = 61309273740

Therefore, the lowest common multiple of 439,780,397,902 is 61309273740.

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.

439 x 780 x 397 x 902 = 122618547480

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.

439 : 1, 439

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

397 : 1, 397

902 : 1, 2, 11, 22, 41, 82, 451, 902

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 439,780,397,902, is 1.

Now, the common factors can be found like this.

439:439

780:2x 2x 3x 5x 13

397:397

902:2x 11x 41

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

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 = 122618547480/(1x2)

LCM = 122618547480/2

LCM = 61309273740

Thus, we can understand that the LCM of 439,780,397,902 is 61309273740.
