Given numbers are 598,780,851,992
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 598,780,851,992 is 164617440.
Find LCM of 598,780,851,992 with Prime Factorization
| 2 | 598, 780, 851, 992 |
| 2 | 299, 390, 851, 496 |
| 13 | 299, 195, 851, 248 |
| 23 | 23, 15, 851, 248 |
| 1, 15, 37, 248 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 23 x 1 x 15 x 37 x 248 = 164617440
Therefore, the lowest common multiple of 598,780,851,992 is 164617440.
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.
598 x 780 x 851 x 992 = 393764916480
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.
598 : 1, 2, 13, 23, 26, 46, 299, 598
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
851 : 1, 23, 37, 851
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 598,780,851,992, is 1.
Now, the common factors can be found like this.
598:2x 13x 23
780:2x 2x 3x 5x 13
851:23x 37
992:2x 2x 2x 2x 2x 31
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 2x 13x 23 = 2392
Therefore, the value for common factors is 2392.
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 = 393764916480/(1x2392)
LCM = 393764916480/2392
LCM = 164617440
Thus, we can understand that the LCM of 598,780,851,992 is 164617440.
