Calculate the LCM of 769,642,746,769

Given numbers are 769,642,746,769

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

The LCM of 769,642,746,769 is 184149354.

Find LCM of 769,642,746,769 with Prime Factorization


2 769, 642, 746, 769
769 769, 321, 373, 769
1, 321, 373, 1

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

2 x 769 x 1 x 321 x 373 x 1 = 184149354

Therefore, the lowest common multiple of 769,642,746,769 is 184149354.

LCM Formula to Find Lowest Common Multiple of 769,642,746,769

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.

769 x 642 x 746 x 769 = 283221706452

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.

769 : 1, 769

642 : 1, 2, 3, 6, 107, 214, 321, 642

746 : 1, 2, 373, 746

769 : 1, 769

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,642,746,769, is 1.

Now, the common factors can be found like this.

769:769

642:2x 3x 107

746:2x 373

769:769

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 769 = 1538

Therefore, the value for common factors is 1538.

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 = 283221706452/(1x1538)

LCM = 283221706452/1538

LCM = 184149354

Thus, we can understand that the LCM of 769,642,746,769 is 184149354.
