Given numbers are 942,698,121,989

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

The LCM of 942,698,121,989 is 39342141102.

Find LCM of 942,698,121,989 with Prime Factorization

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

2 x 471 x 349 x 121 x 989 = 39342141102

Therefore, the lowest common multiple of 942,698,121,989 is 39342141102.

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.

942 x 698 x 121 x 989 = 78684282204

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.

942 : 1, 2, 3, 6, 157, 314, 471, 942

698 : 1, 2, 349, 698

121 : 1, 11, 121

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,698,121,989, is 1.

Now, the common factors can be found like this.

942:2x 3x 157

698:2x 349

121:11x 11

989:23x 43

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 = 78684282204/(1x2)

LCM = 78684282204/2

LCM = 39342141102

Thus, we can understand that the LCM of 942,698,121,989 is 39342141102.
