Calculate the LCM of 785,634,678,698,730

Given numbers are 785,634,678,698,730

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

The LCM of 785,634,678,698,730 is 4298400716070.

Find LCM of 785,634,678,698,730 with Prime Factorization


2 785, 634, 678, 698, 730
5 785, 317, 339, 349, 365
157, 317, 339, 349, 73

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

2 x 5 x 157 x 317 x 339 x 349 x 73 = 4298400716070

Therefore, the lowest common multiple of 785,634,678,698,730 is 4298400716070.

LCM Formula to Find Lowest Common Multiple of 785,634,678,698,730

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.

785 x 634 x 678 x 698 x 730 = 171936028642800

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.

785 : 1, 5, 157, 785

634 : 1, 2, 317, 634

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

698 : 1, 2, 349, 698

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,634,678,698,730, is 1.

Now, the common factors can be found like this.

785:5x 157

634:2x 317

678:2x 3x 113

698:2x 349

730:2x 5x 73

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 5 = 40

Therefore, the value for common factors is 40.

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 = 171936028642800/(1x40)

LCM = 171936028642800/40

LCM = 4298400716070

Thus, we can understand that the LCM of 785,634,678,698,730 is 4298400716070.
