Given numbers are 639,820,346,912,199

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

The LCM of 639,820,346,912,199 is 1370968518960.

Find LCM of 639,820,346,912,199 with Prime Factorization

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

2 x 2 x 3 x 213 x 205 x 173 x 76 x 199 = 1370968518960

Therefore, the lowest common multiple of 639,820,346,912,199 is 1370968518960.

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.

639 x 820 x 346 x 912 x 199 = 32903244455040

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.

639 : 1, 3, 9, 71, 213, 639

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

346 : 1, 2, 173, 346

912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912

199 : 1, 199

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,820,346,912,199, is 1.

Now, the common factors can be found like this.

639:3x 3x 71

820:2x 2x 5x 41

346:2x 173

912:2x 2x 2x 2x 3x 19

199:199

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

2x 2x 2x 3 = 24

Therefore, the value for common factors is 24.

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 = 32903244455040/(1x24)

LCM = 32903244455040/24

LCM = 1370968518960

Thus, we can understand that the LCM of 639,820,346,912,199 is 1370968518960.
