Calculate the LCM of 491,253,147,280

Given numbers are 491,253,147,280

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

The LCM of 491,253,147,280 is 730431240.

Find LCM of 491,253,147,280 with Prime Factorization


7 491, 253, 147, 280
491, 253, 21, 40

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

7 x 491 x 253 x 21 x 40 = 730431240

Therefore, the lowest common multiple of 491,253,147,280 is 730431240.

LCM Formula to Find Lowest Common Multiple of 491,253,147,280

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.

491 x 253 x 147 x 280 = 5113018680

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.

491 : 1, 491

253 : 1, 11, 23, 253

147 : 1, 3, 7, 21, 49, 147

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,253,147,280, is 1.

Now, the common factors can be found like this.

491:491

253:11x 23

147:3x 7x 7

280:2x 2x 2x 5x 7

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7 = 7

Therefore, the value for common factors is 7.

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 = 5113018680/(1x7)

LCM = 5113018680/7

LCM = 730431240

Thus, we can understand that the LCM of 491,253,147,280 is 730431240.
