Calculate the LCM of 655,153,615,878

Given numbers are 655,153,615,878

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

The LCM of 655,153,615,878 is 3607539570.

Find LCM of 655,153,615,878 with Prime Factorization


3 655, 153, 615, 878
5 655, 51, 205, 878
131, 51, 41, 878

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

3 x 5 x 131 x 51 x 41 x 878 = 3607539570

Therefore, the lowest common multiple of 655,153,615,878 is 3607539570.

LCM Formula to Find Lowest Common Multiple of 655,153,615,878

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.

655 x 153 x 615 x 878 = 54113093550

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.

655 : 1, 5, 131, 655

153 : 1, 3, 9, 17, 51, 153

615 : 1, 3, 5, 15, 41, 123, 205, 615

878 : 1, 2, 439, 878

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,153,615,878, is 1.

Now, the common factors can be found like this.

655:5x 131

153:3x 3x 17

615:3x 5x 41

878:2x 439

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

3x 5 = 15

Therefore, the value for common factors is 15.

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 = 54113093550/(1x15)

LCM = 54113093550/15

LCM = 3607539570

Thus, we can understand that the LCM of 655,153,615,878 is 3607539570.
