Calculate the LCM of 779,690,123,549

Given numbers are 779,690,123,549

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

The LCM of 779,690,123,549 is 98364330.

Find LCM of 779,690,123,549 with Prime Factorization


3 779, 690, 123, 549
41 779, 230, 41, 183
19, 230, 1, 183

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

3 x 41 x 19 x 230 x 1 x 183 = 98364330

Therefore, the lowest common multiple of 779,690,123,549 is 98364330.

LCM Formula to Find Lowest Common Multiple of 779,690,123,549

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.

779 x 690 x 123 x 549 = 36296437770

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.

779 : 1, 19, 41, 779

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

123 : 1, 3, 41, 123

549 : 1, 3, 9, 61, 183, 549

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 779,690,123,549, is 1.

Now, the common factors can be found like this.

779:19x 41

690:2x 3x 5x 23

123:3x 41

549:3x 3x 61

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

3x 3x 41 = 369

Therefore, the value for common factors is 369.

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 = 36296437770/(1x369)

LCM = 36296437770/369

LCM = 98364330

Thus, we can understand that the LCM of 779,690,123,549 is 98364330.
