Calculate the LCM of 874,678,117,421

Given numbers are 874,678,117,421

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

The LCM of 874,678,117,421 is 4864719834.

Find LCM of 874,678,117,421 with Prime Factorization


2 874, 678, 117, 421
3 437, 339, 117, 421
437, 113, 39, 421

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

2 x 3 x 437 x 113 x 39 x 421 = 4864719834

Therefore, the lowest common multiple of 874,678,117,421 is 4864719834.

LCM Formula to Find Lowest Common Multiple of 874,678,117,421

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.

874 x 678 x 117 x 421 = 29188319004

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.

874 : 1, 2, 19, 23, 38, 46, 437, 874

678 : 1, 2, 3, 6, 113, 226, 339, 678

117 : 1, 3, 9, 13, 39, 117

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,678,117,421, is 1.

Now, the common factors can be found like this.

874:2x 19x 23

678:2x 3x 113

117:3x 3x 13

421:421

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 29188319004/(1x6)

LCM = 29188319004/6

LCM = 4864719834

Thus, we can understand that the LCM of 874,678,117,421 is 4864719834.
