Given numbers are 839,145,748,392,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 839,145,748,392,820 is 365629722920.
Find LCM of 839,145,748,392,820 with Prime Factorization
| 2 | 839, 145, 748, 392, 820 |
| 2 | 839, 145, 374, 196, 410 |
| 5 | 839, 145, 187, 98, 205 |
| 839, 29, 187, 98, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 839 x 29 x 187 x 98 x 41 = 365629722920
Therefore, the lowest common multiple of 839,145,748,392,820 is 365629722920.
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.
839 x 145 x 748 x 392 x 820 = 29250377833600
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.
839 : 1, 839
145 : 1, 5, 29, 145
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 839,145,748,392,820, is 1.
Now, the common factors can be found like this.
839:839
145:5x 29
748:2x 2x 11x 17
392:2x 2x 2x 7x 7
820:2x 2x 5x 41
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 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 29250377833600/(1x80)
LCM = 29250377833600/80
LCM = 365629722920
Thus, we can understand that the LCM of 839,145,748,392,820 is 365629722920.
