Calculate the LCM of 898,478,872,784

Given numbers are 898,478,872,784

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

The LCM of 898,478,872,784 is 9170368816.

Find LCM of 898,478,872,784 with Prime Factorization


2 898, 478, 872, 784
2 449, 239, 436, 392
2 449, 239, 218, 196
449, 239, 109, 98

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

2 x 2 x 2 x 449 x 239 x 109 x 98 = 9170368816

Therefore, the lowest common multiple of 898,478,872,784 is 9170368816.

LCM Formula to Find Lowest Common Multiple of 898,478,872,784

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.

898 x 478 x 872 x 784 = 293451802112

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.

898 : 1, 2, 449, 898

478 : 1, 2, 239, 478

872 : 1, 2, 4, 8, 109, 218, 436, 872

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

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 898,478,872,784, is 2.

Now, the common factors can be found like this.

898:2x 449

478:2x 239

872:2x 2x 2x 109

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 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 293451802112/(2x16)

LCM = 293451802112/32

LCM = 9170368816

Thus, we can understand that the LCM of 898,478,872,784 is 9170368816.
