Calculate the LCM of 678,169,745,644

Given numbers are 678,169,745,644

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

The LCM of 678,169,745,644 is 27487075980.

Find LCM of 678,169,745,644 with Prime Factorization


2 678, 169, 745, 644
339, 169, 745, 322

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

2 x 339 x 169 x 745 x 322 = 27487075980

Therefore, the lowest common multiple of 678,169,745,644 is 27487075980.

LCM Formula to Find Lowest Common Multiple of 678,169,745,644

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.

678 x 169 x 745 x 644 = 54974151960

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.

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

169 : 1, 13, 169

745 : 1, 5, 149, 745

644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,169,745,644, is 1.

Now, the common factors can be found like this.

678:2x 3x 113

169:13x 13

745:5x 149

644:2x 2x 7x 23

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 = 54974151960/(1x2)

LCM = 54974151960/2

LCM = 27487075980

Thus, we can understand that the LCM of 678,169,745,644 is 27487075980.
