Calculate the LCM of 417,753,146,561,784

Given numbers are 417,753,146,561,784

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

The LCM of 417,753,146,561,784 is 1120186426128.

Find LCM of 417,753,146,561,784 with Prime Factorization


2 417, 753, 146, 561, 784
3 417, 753, 73, 561, 392
139, 251, 73, 187, 392

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

2 x 3 x 139 x 251 x 73 x 187 x 392 = 1120186426128

Therefore, the lowest common multiple of 417,753,146,561,784 is 1120186426128.

LCM Formula to Find Lowest Common Multiple of 417,753,146,561,784

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.

417 x 753 x 146 x 561 x 784 = 20163355670304

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.

417 : 1, 3, 139, 417

753 : 1, 3, 251, 753

146 : 1, 2, 73, 146

561 : 1, 3, 11, 17, 33, 51, 187, 561

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 417,753,146,561,784, is 1.

Now, the common factors can be found like this.

417:3x 139

753:3x 251

146:2x 73

561:3x 11x 17

784:2x 2x 2x 2x 7x 7

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 20163355670304/(1x18)

LCM = 20163355670304/18

LCM = 1120186426128

Thus, we can understand that the LCM of 417,753,146,561,784 is 1120186426128.
