Calculate the LCM of 961,138,578,535

Given numbers are 961,138,578,535

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

The LCM of 961,138,578,535 is 20504732070.

Find LCM of 961,138,578,535 with Prime Factorization


2 961, 138, 578, 535
961, 69, 289, 535

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

2 x 961 x 69 x 289 x 535 = 20504732070

Therefore, the lowest common multiple of 961,138,578,535 is 20504732070.

LCM Formula to Find Lowest Common Multiple of 961,138,578,535

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.

961 x 138 x 578 x 535 = 41009464140

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.

961 : 1, 31, 961

138 : 1, 2, 3, 6, 23, 46, 69, 138

578 : 1, 2, 17, 34, 289, 578

535 : 1, 5, 107, 535

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,138,578,535, is 1.

Now, the common factors can be found like this.

961:31x 31

138:2x 3x 23

578:2x 17x 17

535:5x 107

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 = 41009464140/(1x2)

LCM = 41009464140/2

LCM = 20504732070

Thus, we can understand that the LCM of 961,138,578,535 is 20504732070.
