Given numbers are 645,221,553,652,524

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

The LCM of 645,221,553,652,524 is 6732804607620.

Find LCM of 645,221,553,652,524 with Prime Factorization

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

2 x 2 x 645 x 221 x 553 x 163 x 131 = 6732804607620

Therefore, the lowest common multiple of 645,221,553,652,524 is 6732804607620.

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.

645 x 221 x 553 x 652 x 524 = 26931218430480

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.

645 : 1, 3, 5, 15, 43, 129, 215, 645

221 : 1, 13, 17, 221

553 : 1, 7, 79, 553

652 : 1, 2, 4, 163, 326, 652

524 : 1, 2, 4, 131, 262, 524

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,221,553,652,524, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

221:13x 17

553:7x 79

652:2x 2x 163

524:2x 2x 131

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 26931218430480/(1x4)

LCM = 26931218430480/4

LCM = 6732804607620

Thus, we can understand that the LCM of 645,221,553,652,524 is 6732804607620.
