Given numbers are 521,442,107,756,167

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

The LCM of 521,442,107,756,167 is 1555435623924.

Find LCM of 521,442,107,756,167 with Prime Factorization

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

2 x 521 x 221 x 107 x 378 x 167 = 1555435623924

Therefore, the lowest common multiple of 521,442,107,756,167 is 1555435623924.

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.

521 x 442 x 107 x 756 x 167 = 3110871247848

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.

521 : 1, 521

442 : 1, 2, 13, 17, 26, 34, 221, 442

107 : 1, 107

756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756

167 : 1, 167

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,442,107,756,167, is 1.

Now, the common factors can be found like this.

521:521

442:2x 13x 17

107:107

756:2x 2x 3x 3x 3x 7

167:167

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

2 = 2

Therefore, the value for common factors is 2.

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 = 3110871247848/(1x2)

LCM = 3110871247848/2

LCM = 1555435623924

Thus, we can understand that the LCM of 521,442,107,756,167 is 1555435623924.
