Calculate the LCM of 822,428,151,398

Given numbers are 822,428,151,398

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

The LCM of 822,428,151,398 is 5285859492.

Find LCM of 822,428,151,398 with Prime Factorization


2 822, 428, 151, 398
411, 214, 151, 199

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

2 x 411 x 214 x 151 x 199 = 5285859492

Therefore, the lowest common multiple of 822,428,151,398 is 5285859492.

LCM Formula to Find Lowest Common Multiple of 822,428,151,398

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.

822 x 428 x 151 x 398 = 21143437968

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.

822 : 1, 2, 3, 6, 137, 274, 411, 822

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

151 : 1, 151

398 : 1, 2, 199, 398

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 822,428,151,398, is 1.

Now, the common factors can be found like this.

822:2x 3x 137

428:2x 2x 107

151:151

398:2x 199

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 21143437968/(1x4)

LCM = 21143437968/4

LCM = 5285859492

Thus, we can understand that the LCM of 822,428,151,398 is 5285859492.
