Given numbers are 681,974,642,965

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

The LCM of 681,974,642,965 is 68488421970.

Find LCM of 681,974,642,965 with Prime Factorization

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

2 x 3 x 227 x 487 x 107 x 965 = 68488421970

Therefore, the lowest common multiple of 681,974,642,965 is 68488421970.

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.

681 x 974 x 642 x 965 = 410930531820

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.

681 : 1, 3, 227, 681

974 : 1, 2, 487, 974

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

965 : 1, 5, 193, 965

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 681,974,642,965, is 1.

Now, the common factors can be found like this.

681:3x 227

974:2x 487

642:2x 3x 107

965:5x 193

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 410930531820/(1x6)

LCM = 410930531820/6

LCM = 68488421970

Thus, we can understand that the LCM of 681,974,642,965 is 68488421970.
