Calculate the LCM of 745,494,421,653,515

Given numbers are 745,494,421,653,515

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

The LCM of 745,494,421,653,515 is 10421151833170.

Find LCM of 745,494,421,653,515 with Prime Factorization


5 745, 494, 421, 653, 515
149, 494, 421, 653, 103

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

5 x 149 x 494 x 421 x 653 x 103 = 10421151833170

Therefore, the lowest common multiple of 745,494,421,653,515 is 10421151833170.

LCM Formula to Find Lowest Common Multiple of 745,494,421,653,515

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.

745 x 494 x 421 x 653 x 515 = 52105759165850

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.

745 : 1, 5, 149, 745

494 : 1, 2, 13, 19, 26, 38, 247, 494

421 : 1, 421

653 : 1, 653

515 : 1, 5, 103, 515

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,494,421,653,515, is 1.

Now, the common factors can be found like this.

745:5x 149

494:2x 13x 19

421:421

653:653

515:5x 103

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

5 = 5

Therefore, the value for common factors is 5.

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 = 52105759165850/(1x5)

LCM = 52105759165850/5

LCM = 10421151833170

Thus, we can understand that the LCM of 745,494,421,653,515 is 10421151833170.
