Given numbers are 649,649,620,919

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

The LCM of 649,649,620,919 is 369787220.

Find LCM of 649,649,620,919 with Prime Factorization

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

11 x 59 x 1 x 1 x 620 x 919 = 369787220

Therefore, the lowest common multiple of 649,649,620,919 is 369787220.

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.

649 x 649 x 620 x 919 = 239991905780

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.

649 : 1, 11, 59, 649

649 : 1, 11, 59, 649

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

919 : 1, 919

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,649,620,919, is 1.

Now, the common factors can be found like this.

649:11x 59

649:11x 59

620:2x 2x 5x 31

919:919

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

11x 59 = 649

Therefore, the value for common factors is 649.

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 = 239991905780/(1x649)

LCM = 239991905780/649

LCM = 369787220

Thus, we can understand that the LCM of 649,649,620,919 is 369787220.
