Calculate the LCM of 253,812,992,756

Given numbers are 253,812,992,756

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

The LCM of 253,812,992,756 is 1375599456.

Find LCM of 253,812,992,756 with Prime Factorization


2 253, 812, 992, 756
2 253, 406, 496, 378
7 253, 203, 248, 189
253, 29, 248, 27

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

2 x 2 x 7 x 253 x 29 x 248 x 27 = 1375599456

Therefore, the lowest common multiple of 253,812,992,756 is 1375599456.

LCM Formula to Find Lowest Common Multiple of 253,812,992,756

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.

253 x 812 x 992 x 756 = 154067139072

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.

253 : 1, 11, 23, 253

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

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

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 253,812,992,756, is 1.

Now, the common factors can be found like this.

253:11x 23

812:2x 2x 7x 29

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

756:2x 2x 3x 3x 3x 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 2x 7 = 112

Therefore, the value for common factors is 112.

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 = 154067139072/(1x112)

LCM = 154067139072/112

LCM = 1375599456

Thus, we can understand that the LCM of 253,812,992,756 is 1375599456.
