The LCM of 798,947,641,558 is 45049901778.

Find LCM of 798,947,641,558 with Prime Factorization


2 798, 947, 641, 558
3 399, 947, 641, 279
133, 947, 641, 93

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

2 x 3 x 133 x 947 x 641 x 93 = 45049901778

Therefore, the lowest common multiple of 798,947,641,558 is 45049901778.

LCM Formula to Find Lowest Common Multiple of 798,947,641,558

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.

798 x 947 x 641 x 558 = 270299410668

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.

798 : 1, 2, 3, 6, 7, 14, 19, 21, 38, 42, 57, 114, 133, 266, 399, 798

947 : 1, 947

641 : 1, 641

558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 798,947,641,558, is 1.

Now, the common factors can be found like this.

798:2x 3x 7x 19

947:947

641:641

558:2x 3x 3x 31

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 270299410668/(1x6)

LCM = 270299410668/6

LCM = 45049901778

Thus, we can understand that the LCM of 798,947,641,558 is 45049901778.
