Calculate the LCM of 570,171,637,661

Given numbers are 570,171,637,661

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

The LCM of 570,171,637,661 is 720007470.

Find LCM of 570,171,637,661 with Prime Factorization


3 570, 171, 637, 661
19 190, 57, 637, 661
10, 3, 637, 661

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

3 x 19 x 10 x 3 x 637 x 661 = 720007470

Therefore, the lowest common multiple of 570,171,637,661 is 720007470.

LCM Formula to Find Lowest Common Multiple of 570,171,637,661

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.

570 x 171 x 637 x 661 = 41040425790

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.

570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570

171 : 1, 3, 9, 19, 57, 171

637 : 1, 7, 13, 49, 91, 637

661 : 1, 661

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 570,171,637,661, is 1.

Now, the common factors can be found like this.

570:2x 3x 5x 19

171:3x 3x 19

637:7x 7x 13

661:661

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 41040425790/(1x57)

LCM = 41040425790/57

LCM = 720007470

Thus, we can understand that the LCM of 570,171,637,661 is 720007470.
