The LCM of 579,189,784,381 is 518848848.

Find LCM of 579,189,784,381 with Prime Factorization


3 579, 189, 784, 381
7 193, 63, 784, 127
193, 9, 112, 127

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

3 x 7 x 193 x 9 x 112 x 127 = 518848848

Therefore, the lowest common multiple of 579,189,784,381 is 518848848.

LCM Formula to Find Lowest Common Multiple of 579,189,784,381

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.

579 x 189 x 784 x 381 = 32687477424

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.

579 : 1, 3, 193, 579

189 : 1, 3, 7, 9, 21, 27, 63, 189

784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,189,784,381, is 1.

Now, the common factors can be found like this.

579:3x 193

189:3x 3x 3x 7

784:2x 2x 2x 2x 7x 7

381:3x 127

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 7 = 63

Therefore, the value for common factors is 63.

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 = 32687477424/(1x63)

LCM = 32687477424/63

LCM = 518848848

Thus, we can understand that the LCM of 579,189,784,381 is 518848848.
