Given numbers are 635,675,421,770

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

The LCM of 635,675,421,770 is 5557894650.

Find LCM of 635,675,421,770 with Prime Factorization

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

5 x 127 x 135 x 421 x 154 = 5557894650

Therefore, the lowest common multiple of 635,675,421,770 is 5557894650.

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.

635 x 675 x 421 x 770 = 138947366250

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.

635 : 1, 5, 127, 635

675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675

421 : 1, 421

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,675,421,770, is 1.

Now, the common factors can be found like this.

635:5x 127

675:3x 3x 3x 5x 5

421:421

770:2x 5x 7x 11

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 138947366250/(1x25)

LCM = 138947366250/25

LCM = 5557894650

Thus, we can understand that the LCM of 635,675,421,770 is 5557894650.
