Calculate the LCM of 670,517,784,157,702

Given numbers are 670,517,784,157,702

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

The LCM of 670,517,784,157,702 is 7482697382160.

Find LCM of 670,517,784,157,702 with Prime Factorization


2 670, 517, 784, 157, 702
335, 517, 392, 157, 351

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

2 x 335 x 517 x 392 x 157 x 351 = 7482697382160

Therefore, the lowest common multiple of 670,517,784,157,702 is 7482697382160.

LCM Formula to Find Lowest Common Multiple of 670,517,784,157,702

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.

670 x 517 x 784 x 157 x 702 = 29930789528640

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.

670 : 1, 2, 5, 10, 67, 134, 335, 670

517 : 1, 11, 47, 517

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

157 : 1, 157

702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 670,517,784,157,702, is 1.

Now, the common factors can be found like this.

670:2x 5x 67

517:11x 47

784:2x 2x 2x 2x 7x 7

157:157

702:2x 3x 3x 3x 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 2 = 4

Therefore, the value for common factors is 4.

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 = 29930789528640/(1x4)

LCM = 29930789528640/4

LCM = 7482697382160

Thus, we can understand that the LCM of 670,517,784,157,702 is 7482697382160.
