Given numbers are 689,478,417,695

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

The LCM of 689,478,417,695 is 686678070.

Find LCM of 689,478,417,695 with Prime Factorization

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

139 x 689 x 478 x 3 x 5 = 686678070

Therefore, the lowest common multiple of 689,478,417,695 is 686678070.

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.

689 x 478 x 417 x 695 = 95448251730

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.

689 : 1, 13, 53, 689

478 : 1, 2, 239, 478

417 : 1, 3, 139, 417

695 : 1, 5, 139, 695

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,478,417,695, is 1.

Now, the common factors can be found like this.

689:13x 53

478:2x 239

417:3x 139

695:5x 139

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

139 = 139

Therefore, the value for common factors is 139.

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 = 95448251730/(1x139)

LCM = 95448251730/139

LCM = 686678070

Thus, we can understand that the LCM of 689,478,417,695 is 686678070.
