Calculate the LCM of 440,140,617,549

Given numbers are 440,140,617,549

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

The LCM of 440,140,617,549 is 1043297640.

Find LCM of 440,140,617,549 with Prime Factorization


2 440, 140, 617, 549
2 220, 70, 617, 549
5 110, 35, 617, 549
22, 7, 617, 549

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

2 x 2 x 5 x 22 x 7 x 617 x 549 = 1043297640

Therefore, the lowest common multiple of 440,140,617,549 is 1043297640.

LCM Formula to Find Lowest Common Multiple of 440,140,617,549

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.

440 x 140 x 617 x 549 = 20865952800

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.

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

617 : 1, 617

549 : 1, 3, 9, 61, 183, 549

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,140,617,549, is 1.

Now, the common factors can be found like this.

440:2x 2x 2x 5x 11

140:2x 2x 5x 7

617:617

549:3x 3x 61

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 5 = 20

Therefore, the value for common factors is 20.

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 = 20865952800/(1x20)

LCM = 20865952800/20

LCM = 1043297640

Thus, we can understand that the LCM of 440,140,617,549 is 1043297640.
