Calculate the LCM of 630,722,857,965

Given numbers are 630,722,857,965

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

The LCM of 630,722,857,965 is 37617149430.

Find LCM of 630,722,857,965 with Prime Factorization


2 630, 722, 857, 965
5 315, 361, 857, 965
63, 361, 857, 193

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

2 x 5 x 63 x 361 x 857 x 193 = 37617149430

Therefore, the lowest common multiple of 630,722,857,965 is 37617149430.

LCM Formula to Find Lowest Common Multiple of 630,722,857,965

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.

630 x 722 x 857 x 965 = 376171494300

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

722 : 1, 2, 19, 38, 361, 722

857 : 1, 857

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,722,857,965, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

722:2x 19x 19

857:857

965:5x 193

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 376171494300/(1x10)

LCM = 376171494300/10

LCM = 37617149430

Thus, we can understand that the LCM of 630,722,857,965 is 37617149430.
