Calculate the LCM of 789,789,579,420

Given numbers are 789,789,579,420

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

The LCM of 789,789,579,420 is 21318780.

Find LCM of 789,789,579,420 with Prime Factorization

3	789, 789, 579, 420
263	263, 263, 193, 140
	1, 1, 193, 140

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

3 x 263 x 1 x 1 x 193 x 140 = 21318780

Therefore, the lowest common multiple of 789,789,579,420 is 21318780.

LCM Formula to Find Lowest Common Multiple of 789,789,579,420

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.

789 x 789 x 579 x 420 = 151384656780

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.

789 : 1, 3, 263, 789

579 : 1, 3, 193, 579

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,789,579,420, is 3.

Now, the common factors can be found like this.

789:3x 263

579:3x 193

420:2x 2x 3x 5x 7

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 263 = 2367

Therefore, the value for common factors is 2367.

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 = 151384656780/(3x2367)

LCM = 151384656780/7101

LCM = 21318780

Thus, we can understand that the LCM of 789,789,579,420 is 21318780.
