Given numbers are 642,749,941,607

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

The LCM of 642,749,941,607 is 2566914378.

Find LCM of 642,749,941,607 with Prime Factorization

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

107 x 6 x 7 x 941 x 607 = 2566914378

Therefore, the lowest common multiple of 642,749,941,607 is 2566914378.

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 749 x 941 x 607 = 274659838446

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

749 : 1, 7, 107, 749

941 : 1, 941

607 : 1, 607

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,749,941,607, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

749:7x 107

941:941

607:607

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

107 = 107

Therefore, the value for common factors is 107.

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 = 274659838446/(1x107)

LCM = 274659838446/107

LCM = 2566914378

Thus, we can understand that the LCM of 642,749,941,607 is 2566914378.
