Calculate the LCM of 650,641,852,618

Given numbers are 650,641,852,618

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

The LCM of 650,641,852,618 is 18281768700.

Find LCM of 650,641,852,618 with Prime Factorization


2 650, 641, 852, 618
3 325, 641, 426, 309
325, 641, 142, 103

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

2 x 3 x 325 x 641 x 142 x 103 = 18281768700

Therefore, the lowest common multiple of 650,641,852,618 is 18281768700.

LCM Formula to Find Lowest Common Multiple of 650,641,852,618

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.

650 x 641 x 852 x 618 = 219381224400

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.

650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650

641 : 1, 641

852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852

618 : 1, 2, 3, 6, 103, 206, 309, 618

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,641,852,618, is 1.

Now, the common factors can be found like this.

650:2x 5x 5x 13

641:641

852:2x 2x 3x 71

618:2x 3x 103

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 3 = 12

Therefore, the value for common factors is 12.

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 = 219381224400/(1x12)

LCM = 219381224400/12

LCM = 18281768700

Thus, we can understand that the LCM of 650,641,852,618 is 18281768700.
