Find LCM of 280,706,676,215,623 with Prime Factorization


2 280, 706, 676, 215, 623
2 140, 353, 338, 215, 623
5 70, 353, 169, 215, 623
7 14, 353, 169, 43, 623
2, 353, 169, 43, 89

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

2 x 2 x 5 x 7 x 2 x 353 x 169 x 43 x 89 = 63926054920

Therefore, the lowest common multiple of 280,706,676,215,623 is 63926054920.

LCM Formula to Find Lowest Common Multiple of 280,706,676,215,623

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.

280 x 706 x 676 x 215 x 623 = 17899295377600

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.

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

706 : 1, 2, 353, 706

676 : 1, 2, 4, 13, 26, 52, 169, 338, 676

215 : 1, 5, 43, 215

623 : 1, 7, 89, 623

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,706,676,215,623, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

706:2x 353

676:2x 2x 13x 13

215:5x 43

623:7x 89

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 5x 7 = 280

Therefore, the value for common factors is 280.

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 = 17899295377600/(1x280)

LCM = 17899295377600/280

LCM = 63926054920

Thus, we can understand that the LCM of 280,706,676,215,623 is 63926054920.
