Find LCM of 790,981,649,810,749 with Prime Factorization


2 790, 981, 649, 810, 749
3 395, 981, 649, 405, 749
3 395, 327, 649, 135, 749
5 395, 109, 649, 45, 749
79, 109, 649, 9, 749

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

2 x 3 x 3 x 5 x 79 x 109 x 649 x 9 x 749 = 3390510725910

Therefore, the lowest common multiple of 790,981,649,810,749 is 3390510725910.

LCM Formula to Find Lowest Common Multiple of 790,981,649,810,749

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.

790 x 981 x 649 x 810 x 749 = 305145965331900

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.

790 : 1, 2, 5, 10, 79, 158, 395, 790

981 : 1, 3, 9, 109, 327, 981

649 : 1, 11, 59, 649

810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810

749 : 1, 7, 107, 749

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,981,649,810,749, is 1.

Now, the common factors can be found like this.

790:2x 5x 79

981:3x 3x 109

649:11x 59

810:2x 3x 3x 3x 3x 5

749:7x 107

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 5 = 90

Therefore, the value for common factors is 90.

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 = 305145965331900/(1x90)

LCM = 305145965331900/90

LCM = 3390510725910

Thus, we can understand that the LCM of 790,981,649,810,749 is 3390510725910.
