Given numbers are 420,109,554

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

The LCM of 420,109,554 is 12681060.

Find LCM of 420,109,554 with Prime Factorization

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

2 x 210 x 109 x 277 = 12681060

Therefore, the lowest common multiple of 420,109,554 is 12681060.

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.

420 x 109 x 554 = 25362120

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.

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

109 : 1, 109

554 : 1, 2, 277, 554

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,109,554, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

109:109

554:2x 277

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 = 25362120/(1x2)

LCM = 25362120/2

LCM = 12681060

Thus, we can understand that the LCM of 420,109,554 is 12681060.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 356, 573, 562
