Given numbers are 705,472,649,121

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

The LCM of 705,472,649,121 is 40263960.

Find LCM of 705,472,649,121 with Prime Factorization

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

11 x 59 x 705 x 8 x 1 x 11 = 40263960

Therefore, the lowest common multiple of 705,472,649,121 is 40263960.

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.

705 x 472 x 649 x 121 = 26131310040

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.

705 : 1, 3, 5, 15, 47, 141, 235, 705

472 : 1, 2, 4, 8, 59, 118, 236, 472

649 : 1, 11, 59, 649

121 : 1, 11, 121

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,472,649,121, is 1.

Now, the common factors can be found like this.

705:3x 5x 47

472:2x 2x 2x 59

649:11x 59

121:11x 11

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 = 26131310040/(1x649)

LCM = 26131310040/649

LCM = 40263960

Thus, we can understand that the LCM of 705,472,649,121 is 40263960.
