Given numbers are 639,527,155,509

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

The LCM of 639,527,155,509 is 857036385.

Find LCM of 639,527,155,509 with Prime Factorization

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

31 x 639 x 17 x 5 x 509 = 857036385

Therefore, the lowest common multiple of 639,527,155,509 is 857036385.

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.

639 x 527 x 155 x 509 = 26568127935

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.

639 : 1, 3, 9, 71, 213, 639

527 : 1, 17, 31, 527

155 : 1, 5, 31, 155

509 : 1, 509

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,527,155,509, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

527:17x 31

155:5x 31

509:509

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

31 = 31

Therefore, the value for common factors is 31.

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 = 26568127935/(1x31)

LCM = 26568127935/31

LCM = 857036385

Thus, we can understand that the LCM of 639,527,155,509 is 857036385.
