Given numbers are 623,695,556,221

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

The LCM of 623,695,556,221 is 382758740.

Find LCM of 623,695,556,221 with Prime Factorization

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

139 x 623 x 5 x 4 x 221 = 382758740

Therefore, the lowest common multiple of 623,695,556,221 is 382758740.

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.

623 x 695 x 556 x 221 = 53203464860

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.

623 : 1, 7, 89, 623

695 : 1, 5, 139, 695

556 : 1, 2, 4, 139, 278, 556

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,695,556,221, is 1.

Now, the common factors can be found like this.

623:7x 89

695:5x 139

556:2x 2x 139

221:13x 17

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 = 53203464860/(1x139)

LCM = 53203464860/139

LCM = 382758740

Thus, we can understand that the LCM of 623,695,556,221 is 382758740.
