Calculate the LCM of 865,287,968,438

Given numbers are 865,287,968,438

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

The LCM of 865,287,968,438 is 52628073960.

Find LCM of 865,287,968,438 with Prime Factorization


2 865, 287, 968, 438
865, 287, 484, 219

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

2 x 865 x 287 x 484 x 219 = 52628073960

Therefore, the lowest common multiple of 865,287,968,438 is 52628073960.

LCM Formula to Find Lowest Common Multiple of 865,287,968,438

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.

865 x 287 x 968 x 438 = 105256147920

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.

865 : 1, 5, 173, 865

287 : 1, 7, 41, 287

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

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 865,287,968,438, is 1.

Now, the common factors can be found like this.

865:5x 173

287:7x 41

968:2x 2x 2x 11x 11

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.

2 = 2

Therefore, the value for common factors is 2.

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 = 105256147920/(1x2)

LCM = 105256147920/2

LCM = 52628073960

Thus, we can understand that the LCM of 865,287,968,438 is 52628073960.
