Calculate the LCM of 640,455,493

Given numbers are 640,455,493

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

The LCM of 640,455,493 is 28712320.

Find LCM of 640,455,493 with Prime Factorization

5	640, 455, 493
	128, 91, 493

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

5 x 128 x 91 x 493 = 28712320

Therefore, the lowest common multiple of 640,455,493 is 28712320.

LCM Formula to Find Lowest Common Multiple of 640,455,493

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.

640 x 455 x 493 = 143561600

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.

640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640

455 : 1, 5, 7, 13, 35, 65, 91, 455

493 : 1, 17, 29, 493

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,455,493, is 1.

Now, the common factors can be found like this.

640:2x 2x 2x 2x 2x 2x 2x 5

455:5x 7x 13

493:17x 29

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

5 = 5

Therefore, the value for common factors is 5.

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 = 143561600/(1x5)

LCM = 143561600/5

LCM = 28712320

Thus, we can understand that the LCM of 640,455,493 is 28712320.
