Given numbers are 630,206,980,902,140

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

The LCM of 630,206,980,902,140 is 409715460.

Find LCM of 630,206,980,902,140 with Prime Factorization

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

2 x 2 x 5 x 7 x 9 x 103 x 1 x 451 x 7 = 409715460

Therefore, the lowest common multiple of 630,206,980,902,140 is 409715460.

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.

630 x 206 x 980 x 902 x 140 = 16060846032000

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.

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

206 : 1, 2, 103, 206

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

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

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,206,980,902,140, is 2.

Now, the common factors can be found like this.

630:2x 3x 3x 5x 7

206:2x 103

980:2x 2x 5x 7x 7

902:2x 11x 41

140:2x 2x 5x 7

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 5x 5x 7x 7 = 19600

Therefore, the value for common factors is 19600.

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 = 16060846032000/(2x19600)

LCM = 16060846032000/39200

LCM = 409715460

Thus, we can understand that the LCM of 630,206,980,902,140 is 409715460.
