Given numbers are 771,102,715,549,816

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

The LCM of 771,102,715,549,816 is 27439766640.

Find LCM of 771,102,715,549,816 with Prime Factorization

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

2 x 3 x 17 x 257 x 1 x 715 x 183 x 8 = 27439766640

Therefore, the lowest common multiple of 771,102,715,549,816 is 27439766640.

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.

771 x 102 x 715 x 549 x 816 = 25189705775520

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.

771 : 1, 3, 257, 771

102 : 1, 2, 3, 6, 17, 34, 51, 102

715 : 1, 5, 11, 13, 55, 65, 143, 715

549 : 1, 3, 9, 61, 183, 549

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 771,102,715,549,816, is 1.

Now, the common factors can be found like this.

771:3x 257

102:2x 3x 17

715:5x 11x 13

549:3x 3x 61

816:2x 2x 2x 2x 3x 17

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

2x 3x 3x 3x 17 = 918

Therefore, the value for common factors is 918.

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 = 25189705775520/(1x918)

LCM = 25189705775520/918

LCM = 27439766640

Thus, we can understand that the LCM of 771,102,715,549,816 is 27439766640.
