Given numbers are 637,871,706,987

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

The LCM of 637,871,706,987 is 4248523734.

Find LCM of 637,871,706,987 with Prime Factorization

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

7 x 13 x 7 x 67 x 706 x 141 = 4248523734

Therefore, the lowest common multiple of 637,871,706,987 is 4248523734.

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.

637 x 871 x 706 x 987 = 386615659794

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.

637 : 1, 7, 13, 49, 91, 637

871 : 1, 13, 67, 871

706 : 1, 2, 353, 706

987 : 1, 3, 7, 21, 47, 141, 329, 987

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,871,706,987, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

871:13x 67

706:2x 353

987:3x 7x 47

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

7x 13 = 91

Therefore, the value for common factors is 91.

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 = 386615659794/(1x91)

LCM = 386615659794/91

LCM = 4248523734

Thus, we can understand that the LCM of 637,871,706,987 is 4248523734.
