Given numbers are 840,435,194,970

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

The LCM of 840,435,194,970 is 2362920.

Find LCM of 840,435,194,970 with Prime Factorization

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

2 x 3 x 5 x 97 x 28 x 29 x 1 x 1 = 2362920

Therefore, the lowest common multiple of 840,435,194,970 is 2362920.

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.

840 x 435 x 194 x 970 = 68760972000

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.

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

435 : 1, 3, 5, 15, 29, 87, 145, 435

194 : 1, 2, 97, 194

970 : 1, 2, 5, 10, 97, 194, 485, 970

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,435,194,970, is 1.

Now, the common factors can be found like this.

840:2x 2x 2x 3x 5x 7

435:3x 5x 29

194:2x 97

970:2x 5x 97

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 3x 5x 5x 97 = 29100

Therefore, the value for common factors is 29100.

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 = 68760972000/(1x29100)

LCM = 68760972000/29100

LCM = 2362920

Thus, we can understand that the LCM of 840,435,194,970 is 2362920.
