Find LCM of 611,987,845,642,974 with Prime Factorization


2 611, 987, 845, 642, 974
3 611, 987, 845, 321, 487
13 611, 329, 845, 107, 487
47 47, 329, 65, 107, 487
1, 7, 65, 107, 487

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

2 x 3 x 13 x 47 x 1 x 7 x 65 x 107 x 487 = 86919375270

Therefore, the lowest common multiple of 611,987,845,642,974 is 86919375270.

LCM Formula to Find Lowest Common Multiple of 611,987,845,642,974

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.

611 x 987 x 845 x 642 x 974 = 318646429739820

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.

611 : 1, 13, 47, 611

987 : 1, 3, 7, 21, 47, 141, 329, 987

845 : 1, 5, 13, 65, 169, 845

642 : 1, 2, 3, 6, 107, 214, 321, 642

974 : 1, 2, 487, 974

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 611,987,845,642,974, is 1.

Now, the common factors can be found like this.

611:13x 47

987:3x 7x 47

845:5x 13x 13

642:2x 3x 107

974:2x 487

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

2x 3x 13x 47 = 3666

Therefore, the value for common factors is 3666.

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 = 318646429739820/(1x3666)

LCM = 318646429739820/3666

LCM = 86919375270

Thus, we can understand that the LCM of 611,987,845,642,974 is 86919375270.
