Calculate the LCM of 655,874,785,665

Given numbers are 655,874,785,665

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

The LCM of 655,874,785,665 is 629144530.

Find LCM of 655,874,785,665 with Prime Factorization


5 655, 874, 785, 665
19 131, 874, 157, 133
131, 46, 157, 7

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

5 x 19 x 131 x 46 x 157 x 7 = 629144530

Therefore, the lowest common multiple of 655,874,785,665 is 629144530.

LCM Formula to Find Lowest Common Multiple of 655,874,785,665

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 874 x 785 x 665 = 298843651750

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

874 : 1, 2, 19, 23, 38, 46, 437, 874

785 : 1, 5, 157, 785

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,874,785,665, is 1.

Now, the common factors can be found like this.

655:5x 131

874:2x 19x 23

785:5x 157

665:5x 7x 19

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

5x 5x 19 = 475

Therefore, the value for common factors is 475.

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 = 298843651750/(1x475)

LCM = 298843651750/475

LCM = 629144530

Thus, we can understand that the LCM of 655,874,785,665 is 629144530.
