Given numbers are 642,193,946,210

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

The LCM of 642,193,946,210 is 2051263830.

Find LCM of 642,193,946,210 with Prime Factorization

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

2 x 3 x 107 x 193 x 473 x 35 = 2051263830

Therefore, the lowest common multiple of 642,193,946,210 is 2051263830.

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.

642 x 193 x 946 x 210 = 24615165960

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

193 : 1, 193

946 : 1, 2, 11, 22, 43, 86, 473, 946

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,193,946,210, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

193:193

946:2x 11x 43

210:2x 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.

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 24615165960/(1x12)

LCM = 24615165960/12

LCM = 2051263830

Thus, we can understand that the LCM of 642,193,946,210 is 2051263830.
