Given numbers are 646,616,146,290,650

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

The LCM of 646,616,146,290,650 is 136894958200.

Find LCM of 646,616,146,290,650 with Prime Factorization

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

2 x 5 x 323 x 308 x 73 x 29 x 65 = 136894958200

Therefore, the lowest common multiple of 646,616,146,290,650 is 136894958200.

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 616 x 146 x 290 x 650 = 10951596656000

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

616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616

146 : 1, 2, 73, 146

290 : 1, 2, 5, 10, 29, 58, 145, 290

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,616,146,290,650, is 2.

Now, the common factors can be found like this.

646:2x 17x 19

616:2x 2x 2x 7x 11

146:2x 73

290:2x 5x 29

650:2x 5x 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 5 = 40

Therefore, the value for common factors is 40.

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 = 10951596656000/(2x40)

LCM = 10951596656000/80

LCM = 136894958200

Thus, we can understand that the LCM of 646,616,146,290,650 is 136894958200.
