Calculate the LCM of 640,245,305,653

Given numbers are 640,245,305,653

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

The LCM of 640,245,305,653 is 1249162880.

Find LCM of 640,245,305,653 with Prime Factorization

5	640, 245, 305, 653
	128, 49, 61, 653

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

5 x 128 x 49 x 61 x 653 = 1249162880

Therefore, the lowest common multiple of 640,245,305,653 is 1249162880.

LCM Formula to Find Lowest Common Multiple of 640,245,305,653

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 245 x 305 x 653 = 31229072000

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

245 : 1, 5, 7, 35, 49, 245

305 : 1, 5, 61, 305

653 : 1, 653

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,245,305,653, is 1.

Now, the common factors can be found like this.

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

245:5x 7x 7

305:5x 61

653:653

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 31229072000/(1x25)

LCM = 31229072000/25

LCM = 1249162880

Thus, we can understand that the LCM of 640,245,305,653 is 1249162880.
