Given numbers are 985,994,630,168,438

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

The LCM of 985,994,630,168,438 is 2573048520.

Find LCM of 985,994,630,168,438 with Prime Factorization

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

2 x 3 x 5 x 7 x 197 x 71 x 3 x 4 x 73 = 2573048520

Therefore, the lowest common multiple of 985,994,630,168,438 is 2573048520.

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.

985 x 994 x 630 x 168 x 438 = 45388575892800

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.

985 : 1, 5, 197, 985

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

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

168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,994,630,168,438, is 1.

Now, the common factors can be found like this.

985:5x 197

994:2x 7x 71

630:2x 3x 3x 5x 7

168:2x 2x 2x 3x 7

438:2x 3x 73

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 3x 3x 5x 7x 7 = 17640

Therefore, the value for common factors is 17640.

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 = 45388575892800/(1x17640)

LCM = 45388575892800/17640

LCM = 2573048520

Thus, we can understand that the LCM of 985,994,630,168,438 is 2573048520.
