Given numbers are 657,509,509,220

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

The LCM of 657,509,509,220 is 73570860.

Find LCM of 657,509,509,220 with Prime Factorization

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

509 x 657 x 1 x 1 x 220 = 73570860

Therefore, the lowest common multiple of 657,509,509,220 is 73570860.

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.

657 x 509 x 509 x 220 = 37447567740

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.

657 : 1, 3, 9, 73, 219, 657

509 : 1, 509

509 : 1, 509

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 657,509,509,220, is 1.

Now, the common factors can be found like this.

657:3x 3x 73

509:509

509:509

220:2x 2x 5x 11

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

509 = 509

Therefore, the value for common factors is 509.

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 = 37447567740/(1x509)

LCM = 37447567740/509

LCM = 73570860

Thus, we can understand that the LCM of 657,509,509,220 is 73570860.
