Given numbers are 672,121,340,377

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

The LCM of 672,121,340,377 is 2605643040.

Find LCM of 672,121,340,377 with Prime Factorization

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

2 x 2 x 168 x 121 x 85 x 377 = 2605643040

Therefore, the lowest common multiple of 672,121,340,377 is 2605643040.

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.

672 x 121 x 340 x 377 = 10422572160

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.

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

121 : 1, 11, 121

340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340

377 : 1, 13, 29, 377

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,121,340,377, is 1.

Now, the common factors can be found like this.

672:2x 2x 2x 2x 2x 3x 7

121:11x 11

340:2x 2x 5x 17

377:13x 29

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 10422572160/(1x4)

LCM = 10422572160/4

LCM = 2605643040

Thus, we can understand that the LCM of 672,121,340,377 is 2605643040.
