Calculate the LCM of 428,331,909,178,785

Given numbers are 428,331,909,178,785

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

The LCM of 428,331,909,178,785 is 8996950051380.

Find LCM of 428,331,909,178,785 with Prime Factorization


2 428, 331, 909, 178, 785
214, 331, 909, 89, 785

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

2 x 214 x 331 x 909 x 89 x 785 = 8996950051380

Therefore, the lowest common multiple of 428,331,909,178,785 is 8996950051380.

LCM Formula to Find Lowest Common Multiple of 428,331,909,178,785

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.

428 x 331 x 909 x 178 x 785 = 17993900102760

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.

428 : 1, 2, 4, 107, 214, 428

331 : 1, 331

909 : 1, 3, 9, 101, 303, 909

178 : 1, 2, 89, 178

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,331,909,178,785, is 1.

Now, the common factors can be found like this.

428:2x 2x 107

331:331

909:3x 3x 101

178:2x 89

785:5x 157

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

2 = 2

Therefore, the value for common factors is 2.

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 = 17993900102760/(1x2)

LCM = 17993900102760/2

LCM = 8996950051380

Thus, we can understand that the LCM of 428,331,909,178,785 is 8996950051380.
