Calculate the LCM of 853,978,730,756

Given numbers are 853,978,730,756

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

The LCM of 853,978,730,756 is 38366421660.

Find LCM of 853,978,730,756 with Prime Factorization


2 853, 978, 730, 756
3 853, 489, 365, 378
853, 163, 365, 126

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

2 x 3 x 853 x 163 x 365 x 126 = 38366421660

Therefore, the lowest common multiple of 853,978,730,756 is 38366421660.

LCM Formula to Find Lowest Common Multiple of 853,978,730,756

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.

853 x 978 x 730 x 756 = 460397059920

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.

853 : 1, 853

978 : 1, 2, 3, 6, 163, 326, 489, 978

730 : 1, 2, 5, 10, 73, 146, 365, 730

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 853,978,730,756, is 1.

Now, the common factors can be found like this.

853:853

978:2x 3x 163

730:2x 5x 73

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

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 3 = 12

Therefore, the value for common factors is 12.

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 = 460397059920/(1x12)

LCM = 460397059920/12

LCM = 38366421660

Thus, we can understand that the LCM of 853,978,730,756 is 38366421660.
