Calculate the LCM of 418,131,131,619,721

Given numbers are 418,131,131,619,721

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

The LCM of 418,131,131,619,721 is 24438440642.

Find LCM of 418,131,131,619,721 with Prime Factorization


131 418, 131, 131, 619, 721
418, 1, 1, 619, 721

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

131 x 418 x 1 x 1 x 619 x 721 = 24438440642

Therefore, the lowest common multiple of 418,131,131,619,721 is 24438440642.

LCM Formula to Find Lowest Common Multiple of 418,131,131,619,721

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.

418 x 131 x 131 x 619 x 721 = 3201435724102

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.

418 : 1, 2, 11, 19, 22, 38, 209, 418

131 : 1, 131

131 : 1, 131

619 : 1, 619

721 : 1, 7, 103, 721

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,131,131,619,721, is 1.

Now, the common factors can be found like this.

418:2x 11x 19

131:131

131:131

619:619

721:7x 103

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

131 = 131

Therefore, the value for common factors is 131.

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 = 3201435724102/(1x131)

LCM = 3201435724102/131

LCM = 24438440642

Thus, we can understand that the LCM of 418,131,131,619,721 is 24438440642.
