Calculate the LCM of 438,776,763

Given numbers are 438,776,763

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

The LCM of 438,776,763 is 129667272.

Find LCM of 438,776,763 with Prime Factorization


2 438, 776, 763
219, 388, 763

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

2 x 219 x 388 x 763 = 129667272

Therefore, the lowest common multiple of 438,776,763 is 129667272.

LCM Formula to Find Lowest Common Multiple of 438,776,763

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.

438 x 776 x 763 = 259334544

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.

438 : 1, 2, 3, 6, 73, 146, 219, 438

776 : 1, 2, 4, 8, 97, 194, 388, 776

763 : 1, 7, 109, 763

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,776,763, is 1.

Now, the common factors can be found like this.

438:2x 3x 73

776:2x 2x 2x 97

763:7x 109

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 = 259334544/(1x2)

LCM = 259334544/2

LCM = 129667272

Thus, we can understand that the LCM of 438,776,763 is 129667272.
