Find LCM of 174,817,989,661,858 with Prime Factorization


2 174, 817, 989, 661, 858
3 87, 817, 989, 661, 429
43 29, 817, 989, 661, 143
29, 19, 23, 661, 143

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

2 x 3 x 43 x 29 x 19 x 23 x 661 x 143 = 309055614582

Therefore, the lowest common multiple of 174,817,989,661,858 is 309055614582.

LCM Formula to Find Lowest Common Multiple of 174,817,989,661,858

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.

174 x 817 x 989 x 661 x 858 = 79736348562156

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.

174 : 1, 2, 3, 6, 29, 58, 87, 174

817 : 1, 19, 43, 817

989 : 1, 23, 43, 989

661 : 1, 661

858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 174,817,989,661,858, is 1.

Now, the common factors can be found like this.

174:2x 3x 29

817:19x 43

989:23x 43

661:661

858:2x 3x 11x 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 43 = 258

Therefore, the value for common factors is 258.

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 = 79736348562156/(1x258)

LCM = 79736348562156/258

LCM = 309055614582

Thus, we can understand that the LCM of 174,817,989,661,858 is 309055614582.
