Calculate the LCM of 280,458,776,817

Given numbers are 280,458,776,817

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

The LCM of 280,458,776,817 is 5081445880.

Find LCM of 280,458,776,817 with Prime Factorization


2 280, 458, 776, 817
2 140, 229, 388, 817
2 70, 229, 194, 817
35, 229, 97, 817

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

2 x 2 x 2 x 35 x 229 x 97 x 817 = 5081445880

Therefore, the lowest common multiple of 280,458,776,817 is 5081445880.

LCM Formula to Find Lowest Common Multiple of 280,458,776,817

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.

280 x 458 x 776 x 817 = 81303134080

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.

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

458 : 1, 2, 229, 458

776 : 1, 2, 4, 8, 97, 194, 388, 776

817 : 1, 19, 43, 817

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,458,776,817, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

458:2x 229

776:2x 2x 2x 97

817:19x 43

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 = 81303134080/(1x16)

LCM = 81303134080/16

LCM = 5081445880

Thus, we can understand that the LCM of 280,458,776,817 is 5081445880.
