Given numbers are 906,923,121,639

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

The LCM of 906,923,121,639 is 303554394.

Find LCM of 906,923,121,639 with Prime Factorization

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

3 x 71 x 302 x 13 x 121 x 3 = 303554394

Therefore, the lowest common multiple of 906,923,121,639 is 303554394.

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.

906 x 923 x 121 x 639 = 64657085922

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.

906 : 1, 2, 3, 6, 151, 302, 453, 906

923 : 1, 13, 71, 923

121 : 1, 11, 121

639 : 1, 3, 9, 71, 213, 639

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,923,121,639, is 1.

Now, the common factors can be found like this.

906:2x 3x 151

923:13x 71

121:11x 11

639:3x 3x 71

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

3x 71 = 213

Therefore, the value for common factors is 213.

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 = 64657085922/(1x213)

LCM = 64657085922/213

LCM = 303554394

Thus, we can understand that the LCM of 906,923,121,639 is 303554394.
