Calculate the LCM of 749,151,665,456

Given numbers are 749,151,665,456

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

The LCM of 749,151,665,456 is 257865720.

Find LCM of 749,151,665,456 with Prime Factorization


7 749, 151, 665, 456
19 107, 151, 95, 456
107, 151, 5, 24

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

7 x 19 x 107 x 151 x 5 x 24 = 257865720

Therefore, the lowest common multiple of 749,151,665,456 is 257865720.

LCM Formula to Find Lowest Common Multiple of 749,151,665,456

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.

749 x 151 x 665 x 456 = 34296140760

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.

749 : 1, 7, 107, 749

151 : 1, 151

665 : 1, 5, 7, 19, 35, 95, 133, 665

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,151,665,456, is 1.

Now, the common factors can be found like this.

749:7x 107

151:151

665:5x 7x 19

456:2x 2x 2x 3x 19

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

7x 19 = 133

Therefore, the value for common factors is 133.

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 = 34296140760/(1x133)

LCM = 34296140760/133

LCM = 257865720

Thus, we can understand that the LCM of 749,151,665,456 is 257865720.
