Calculate the LCM of 385,992,473,684

Given numbers are 385,992,473,684

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

The LCM of 385,992,473,684 is 2808257760.

Find LCM of 385,992,473,684 with Prime Factorization


2 385, 992, 473, 684
2 385, 496, 473, 342
11 385, 248, 473, 171
35, 248, 43, 171

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

2 x 2 x 11 x 35 x 248 x 43 x 171 = 2808257760

Therefore, the lowest common multiple of 385,992,473,684 is 2808257760.

LCM Formula to Find Lowest Common Multiple of 385,992,473,684

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.

385 x 992 x 473 x 684 = 123563341440

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.

385 : 1, 5, 7, 11, 35, 55, 77, 385

992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992

473 : 1, 11, 43, 473

684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 385,992,473,684, is 1.

Now, the common factors can be found like this.

385:5x 7x 11

992:2x 2x 2x 2x 2x 31

473:11x 43

684:2x 2x 3x 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.

2x 2x 11 = 44

Therefore, the value for common factors is 44.

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 = 123563341440/(1x44)

LCM = 123563341440/44

LCM = 2808257760

Thus, we can understand that the LCM of 385,992,473,684 is 2808257760.
