Given numbers are 902,545,212,645

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

The LCM of 902,545,212,645 is 6722001660.

Find LCM of 902,545,212,645 with Prime Factorization

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

2 x 5 x 451 x 109 x 106 x 129 = 6722001660

Therefore, the lowest common multiple of 902,545,212,645 is 6722001660.

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.

902 x 545 x 212 x 645 = 67220016600

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.

902 : 1, 2, 11, 22, 41, 82, 451, 902

545 : 1, 5, 109, 545

212 : 1, 2, 4, 53, 106, 212

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,545,212,645, is 1.

Now, the common factors can be found like this.

902:2x 11x 41

545:5x 109

212:2x 2x 53

645:3x 5x 43

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

2x 5 = 10

Therefore, the value for common factors is 10.

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 = 67220016600/(1x10)

LCM = 67220016600/10

LCM = 6722001660

Thus, we can understand that the LCM of 902,545,212,645 is 6722001660.
