Given numbers are 645,451,903,614

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

The LCM of 645,451,903,614 is 1250266710.

Find LCM of 645,451,903,614 with Prime Factorization

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

3 x 43 x 5 x 451 x 7 x 614 = 1250266710

Therefore, the lowest common multiple of 645,451,903,614 is 1250266710.

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 451 x 903 x 614 = 161284405590

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

451 : 1, 11, 41, 451

903 : 1, 3, 7, 21, 43, 129, 301, 903

614 : 1, 2, 307, 614

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,451,903,614, is 1.

Now, the common factors can be found like this.

645:3x 5x 43

451:11x 41

903:3x 7x 43

614:2x 307

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

3x 43 = 129

Therefore, the value for common factors is 129.

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 = 161284405590/(1x129)

LCM = 161284405590/129

LCM = 1250266710

Thus, we can understand that the LCM of 645,451,903,614 is 1250266710.
