Given numbers are 689,422,756,988,942

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

The LCM of 689,422,756,988,942 is 327851161092.

Find LCM of 689,422,756,988,942 with Prime Factorization


2 689, 422, 756, 988, 942
2 689, 211, 378, 494, 471
3 689, 211, 189, 247, 471
13 689, 211, 63, 247, 157
53, 211, 63, 19, 157

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

2 x 2 x 3 x 13 x 53 x 211 x 63 x 19 x 157 = 327851161092

LCM Formula to Find Lowest Common Multiple of 689,422,756,988,942

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.

689 x 422 x 756 x 988 x 942 = 204579124521408

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.

689 : 1, 13, 53, 689

422 : 1, 2, 211, 422

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

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,422,756,988,942, is 1.

Now, the common factors can be found like this.

689:13x 53

422:2x 211

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

988:2x 2x 13x 19

942:2x 3x 157

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

2x 2x 2x 2x 3x 13 = 624

Therefore, the value for common factors is 624.

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 = 204579124521408/(1x624)

LCM = 204579124521408/624

LCM = 327851161092

Thus, we can understand that the LCM of 689,422,756,988,942 is 327851161092.
