Given numbers are 520,102,985,103,816

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

The LCM of 520,102,985,103,816 is 1076234640.

Find LCM of 520,102,985,103,816 with Prime Factorization

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

2 x 2 x 2 x 3 x 5 x 17 x 13 x 1 x 197 x 103 x 2 = 1076234640

Therefore, the lowest common multiple of 520,102,985,103,816 is 1076234640.

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.

520 x 102 x 985 x 103 x 816 = 4391037331200

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.

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

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

985 : 1, 5, 197, 985

103 : 1, 103

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 520,102,985,103,816, is 1.

Now, the common factors can be found like this.

520:2x 2x 2x 5x 13

102:2x 3x 17

985:5x 197

103:103

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 2x 2x 2x 3x 5x 17 = 4080

Therefore, the value for common factors is 4080.

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 = 4391037331200/(1x4080)

LCM = 4391037331200/4080

LCM = 1076234640

Thus, we can understand that the LCM of 520,102,985,103,816 is 1076234640.
