Find LCM of 821,242,847,602,159 with Prime Factorization


2 821, 242, 847, 602, 159
7 821, 121, 847, 301, 159
11 821, 121, 121, 43, 159
11 821, 11, 11, 43, 159
821, 1, 1, 43, 159

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

2 x 7 x 11 x 11 x 821 x 1 x 1 x 43 x 159 = 9508721838

Therefore, the lowest common multiple of 821,242,847,602,159 is 9508721838.

LCM Formula to Find Lowest Common Multiple of 821,242,847,602,159

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.

821 x 242 x 847 x 602 x 159 = 16107774793572

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.

821 : 1, 821

242 : 1, 2, 11, 22, 121, 242

847 : 1, 7, 11, 77, 121, 847

602 : 1, 2, 7, 14, 43, 86, 301, 602

159 : 1, 3, 53, 159

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,242,847,602,159, is 1.

Now, the common factors can be found like this.

821:821

242:2x 11x 11

847:7x 11x 11

602:2x 7x 43

159:3x 53

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

2x 7x 11x 11 = 1694

Therefore, the value for common factors is 1694.

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 = 16107774793572/(1x1694)

LCM = 16107774793572/1694

LCM = 9508721838

Thus, we can understand that the LCM of 821,242,847,602,159 is 9508721838.
