Find LCM of 865,756,806,387,975 with Prime Factorization


2 865, 756, 806, 387, 975
3 865, 378, 403, 387, 975
3 865, 126, 403, 129, 325
5 865, 42, 403, 43, 325
13 173, 42, 403, 43, 65
173, 42, 31, 43, 5

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

2 x 3 x 3 x 5 x 13 x 173 x 42 x 31 x 43 x 5 = 56660631300

Therefore, the lowest common multiple of 865,756,806,387,975 is 56660631300.

LCM Formula to Find Lowest Common Multiple of 865,756,806,387,975

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.

865 x 756 x 806 x 387 x 975 = 198878815863000

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.

865 : 1, 5, 173, 865

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

806 : 1, 2, 13, 26, 31, 62, 403, 806

387 : 1, 3, 9, 43, 129, 387

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,756,806,387,975, is 1.

Now, the common factors can be found like this.

865:5x 173

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

806:2x 13x 31

387:3x 3x 43

975:3x 5x 5x 13

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 3x 3x 5x 13 = 3510

Therefore, the value for common factors is 3510.

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 = 198878815863000/(1x3510)

LCM = 198878815863000/3510

LCM = 56660631300

Thus, we can understand that the LCM of 865,756,806,387,975 is 56660631300.
