Calculate the LCM of 869,675,704,142

Given numbers are 869,675,704,142

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

The LCM of 869,675,704,142 is 2665396800.

Find LCM of 869,675,704,142 with Prime Factorization


2 869, 675, 704, 142
11 869, 675, 352, 71
79, 675, 32, 71

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

2 x 11 x 79 x 675 x 32 x 71 = 2665396800

Therefore, the lowest common multiple of 869,675,704,142 is 2665396800.

LCM Formula to Find Lowest Common Multiple of 869,675,704,142

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.

869 x 675 x 704 x 142 = 58638729600

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.

869 : 1, 11, 79, 869

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 869,675,704,142, is 1.

Now, the common factors can be found like this.

869:11x 79

675:3x 3x 3x 5x 5

704:2x 2x 2x 2x 2x 2x 11

142:2x 71

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 58638729600/(1x22)

LCM = 58638729600/22

LCM = 2665396800

Thus, we can understand that the LCM of 869,675,704,142 is 2665396800.
