Find LCM of 836,247,220,661,354 with Prime Factorization


2 836, 247, 220, 661, 354
2 418, 247, 110, 661, 177
11 209, 247, 55, 661, 177
19 19, 247, 5, 661, 177
1, 13, 5, 661, 177

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

2 x 2 x 11 x 19 x 1 x 13 x 5 x 661 x 177 = 6357616980

Therefore, the lowest common multiple of 836,247,220,661,354 is 6357616980.

LCM Formula to Find Lowest Common Multiple of 836,247,220,661,354

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.

836 x 247 x 220 x 661 x 354 = 10629935590560

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.

836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836

247 : 1, 13, 19, 247

220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220

661 : 1, 661

354 : 1, 2, 3, 6, 59, 118, 177, 354

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 836,247,220,661,354, is 1.

Now, the common factors can be found like this.

836:2x 2x 11x 19

247:13x 19

220:2x 2x 5x 11

661:661

354:2x 3x 59

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 2x 11x 19 = 1672

Therefore, the value for common factors is 1672.

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 = 10629935590560/(1x1672)

LCM = 10629935590560/1672

LCM = 6357616980

Thus, we can understand that the LCM of 836,247,220,661,354 is 6357616980.
