Calculate the LCM of 291,630,280,478

Given numbers are 291,630,280,478

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 291,630,280,478 is 58421160.

Find LCM of 291,630,280,478 with Prime Factorization


2 291, 630, 280, 478
3 291, 315, 140, 239
5 97, 105, 140, 239
7 97, 21, 28, 239
97, 3, 4, 239

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

2 x 3 x 5 x 7 x 97 x 3 x 4 x 239 = 58421160

Therefore, the lowest common multiple of 291,630,280,478 is 58421160.

LCM Formula to Find Lowest Common Multiple of 291,630,280,478

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.

291 x 630 x 280 x 478 = 24536887200

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.

291 : 1, 3, 97, 291

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

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

478 : 1, 2, 239, 478

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,630,280,478, is 1.

Now, the common factors can be found like this.

291:3x 97

630:2x 3x 3x 5x 7

280:2x 2x 2x 5x 7

478:2x 239

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 5x 7 = 420

Therefore, the value for common factors is 420.

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 = 24536887200/(1x420)

LCM = 24536887200/420

LCM = 58421160

Thus, we can understand that the LCM of 291,630,280,478 is 58421160.
