Given numbers are 961,618,638,473

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

The LCM of 961,618,638,473 is 8146498866.

Find LCM of 961,618,638,473 with Prime Factorization

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

2 x 11 x 961 x 309 x 29 x 43 = 8146498866

Therefore, the lowest common multiple of 961,618,638,473 is 8146498866.

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.

961 x 618 x 638 x 473 = 179222975052

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.

961 : 1, 31, 961

618 : 1, 2, 3, 6, 103, 206, 309, 618

638 : 1, 2, 11, 22, 29, 58, 319, 638

473 : 1, 11, 43, 473

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,618,638,473, is 1.

Now, the common factors can be found like this.

961:31x 31

618:2x 3x 103

638:2x 11x 29

473:11x 43

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

2x 11 = 22

Therefore, the value for common factors is 22.

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 = 179222975052/(1x22)

LCM = 179222975052/22

LCM = 8146498866

Thus, we can understand that the LCM of 961,618,638,473 is 8146498866.
