Given numbers are 646,610,190,133,780

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

The LCM of 646,610,190,133,780 is 107578380.

Find LCM of 646,610,190,133,780 with Prime Factorization

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

2 x 5 x 19 x 17 x 61 x 1 x 7 x 78 = 107578380

Therefore, the lowest common multiple of 646,610,190,133,780 is 107578380.

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.

646 x 610 x 190 x 133 x 780 = 7767159036000

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

610 : 1, 2, 5, 10, 61, 122, 305, 610

190 : 1, 2, 5, 10, 19, 38, 95, 190

133 : 1, 7, 19, 133

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,610,190,133,780, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

610:2x 5x 61

190:2x 5x 19

133:7x 19

780:2x 2x 3x 5x 13

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 5x 5x 19x 19 = 72200

Therefore, the value for common factors is 72200.

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 = 7767159036000/(1x72200)

LCM = 7767159036000/72200

LCM = 107578380

Thus, we can understand that the LCM of 646,610,190,133,780 is 107578380.
