Calculate the LCM of 620,354,658,381

Given numbers are 620,354,658,381

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

The LCM of 620,354,658,381 is 4585266420.

Find LCM of 620,354,658,381 with Prime Factorization


2 620, 354, 658, 381
3 310, 177, 329, 381
310, 59, 329, 127

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

2 x 3 x 310 x 59 x 329 x 127 = 4585266420

Therefore, the lowest common multiple of 620,354,658,381 is 4585266420.

LCM Formula to Find Lowest Common Multiple of 620,354,658,381

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.

620 x 354 x 658 x 381 = 55023197040

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.

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

354 : 1, 2, 3, 6, 59, 118, 177, 354

658 : 1, 2, 7, 14, 47, 94, 329, 658

381 : 1, 3, 127, 381

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,354,658,381, is 1.

Now, the common factors can be found like this.

620:2x 2x 5x 31

354:2x 3x 59

658:2x 7x 47

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.

2x 2x 3 = 12

Therefore, the value for common factors is 12.

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 = 55023197040/(1x12)

LCM = 55023197040/12

LCM = 4585266420

Thus, we can understand that the LCM of 620,354,658,381 is 4585266420.
