Given numbers are 212,994,860,781,440

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

The LCM of 212,994,860,781,440 is 498371720.

Find LCM of 212,994,860,781,440 with Prime Factorization

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

2 x 2 x 5 x 11 x 71 x 53 x 7 x 43 x 1 x 2 = 498371720

Therefore, the lowest common multiple of 212,994,860,781,440 is 498371720.

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.

212 x 994 x 860 x 781 x 440 = 62276530131200

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.

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

994 : 1, 2, 7, 14, 71, 142, 497, 994

860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860

781 : 1, 11, 71, 781

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 212,994,860,781,440, is 1.

Now, the common factors can be found like this.

212:2x 2x 53

994:2x 7x 71

860:2x 2x 5x 43

781:11x 71

440:2x 2x 2x 5x 11

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

2x 2x 2x 2x 2x 5x 11x 71 = 124960

Therefore, the value for common factors is 124960.

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 = 62276530131200/(1x124960)

LCM = 62276530131200/124960

LCM = 498371720

Thus, we can understand that the LCM of 212,994,860,781,440 is 498371720.
