Given numbers are 554,461,420

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

The LCM of 554,461,420 is 53632740.

Find LCM of 554,461,420 with Prime Factorization

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

2 x 277 x 461 x 210 = 53632740

Therefore, the lowest common multiple of 554,461,420 is 53632740.

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.

554 x 461 x 420 = 107265480

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.

554 : 1, 2, 277, 554

461 : 1, 461

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 554,461,420, is 1.

Now, the common factors can be found like this.

554:2x 277

461:461

420:2x 2x 3x 5x 7

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

2 = 2

Therefore, the value for common factors is 2.

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 = 107265480/(1x2)

LCM = 107265480/2

LCM = 53632740

Thus, we can understand that the LCM of 554,461,420 is 53632740.
