Given numbers are 217,402,970,715

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

The LCM of 217,402,970,715 is 6050114070.

Find LCM of 217,402,970,715 with Prime Factorization

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

2 x 5 x 217 x 201 x 97 x 143 = 6050114070

Therefore, the lowest common multiple of 217,402,970,715 is 6050114070.

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.

217 x 402 x 970 x 715 = 60501140700

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.

217 : 1, 7, 31, 217

402 : 1, 2, 3, 6, 67, 134, 201, 402

970 : 1, 2, 5, 10, 97, 194, 485, 970

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,402,970,715, is 1.

Now, the common factors can be found like this.

217:7x 31

402:2x 3x 67

970:2x 5x 97

715:5x 11x 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 5 = 10

Therefore, the value for common factors is 10.

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 = 60501140700/(1x10)

LCM = 60501140700/10

LCM = 6050114070

Thus, we can understand that the LCM of 217,402,970,715 is 6050114070.
