Calculate the LCM of 747,549,551,686,186

Given numbers are 747,549,551,686,186

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

The LCM of 747,549,551,686,186 is 533934329922.

Find LCM of 747,549,551,686,186 with Prime Factorization


2 747, 549, 551, 686, 186
3 747, 549, 551, 343, 93
3 249, 183, 551, 343, 31
83, 61, 551, 343, 31

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

2 x 3 x 3 x 83 x 61 x 551 x 343 x 31 = 533934329922

Therefore, the lowest common multiple of 747,549,551,686,186 is 533934329922.

LCM Formula to Find Lowest Common Multiple of 747,549,551,686,186

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.

747 x 549 x 551 x 686 x 186 = 28832453815788

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.

747 : 1, 3, 9, 83, 249, 747

549 : 1, 3, 9, 61, 183, 549

551 : 1, 19, 29, 551

686 : 1, 2, 7, 14, 49, 98, 343, 686

186 : 1, 2, 3, 6, 31, 62, 93, 186

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,549,551,686,186, is 1.

Now, the common factors can be found like this.

747:3x 3x 83

549:3x 3x 61

551:19x 29

686:2x 7x 7x 7

186:2x 3x 31

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

2x 3x 3x 3 = 54

Therefore, the value for common factors is 54.

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 = 28832453815788/(1x54)

LCM = 28832453815788/54

LCM = 533934329922

Thus, we can understand that the LCM of 747,549,551,686,186 is 533934329922.
