Find LCM of 630,681,674,678,465 with Prime Factorization


2 630, 681, 674, 678, 465
3 315, 681, 337, 339, 465
5 105, 227, 337, 113, 155
21, 227, 337, 113, 31

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

2 x 3 x 5 x 21 x 227 x 337 x 113 x 31 = 168824878110

Therefore, the lowest common multiple of 630,681,674,678,465 is 168824878110.

LCM Formula to Find Lowest Common Multiple of 630,681,674,678,465

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.

630 x 681 x 674 x 678 x 465 = 91165434179400

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

681 : 1, 3, 227, 681

674 : 1, 2, 337, 674

678 : 1, 2, 3, 6, 113, 226, 339, 678

465 : 1, 3, 5, 15, 31, 93, 155, 465

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,681,674,678,465, is 1.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

681:3x 227

674:2x 337

678:2x 3x 113

465:3x 5x 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 2x 3x 3x 3x 5 = 540

Therefore, the value for common factors is 540.

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 = 91165434179400/(1x540)

LCM = 91165434179400/540

LCM = 168824878110

Thus, we can understand that the LCM of 630,681,674,678,465 is 168824878110.
