The LCM of 979,748,740,225 is 554211900.
Find LCM of 979,748,740,225 with Prime Factorization
| 2 | 979, 748, 740, 225 |
| 2 | 979, 374, 370, 225 |
| 5 | 979, 187, 185, 225 |
| 11 | 979, 187, 37, 45 |
| 89, 17, 37, 45 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 89 x 17 x 37 x 45 = 554211900
Therefore, the lowest common multiple of 979,748,740,225 is 554211900.
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.
979 x 748 x 740 x 225 = 121926618000
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.
979 : 1, 11, 89, 979
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,748,740,225, is 1.
Now, the common factors can be found like this.
979:11x 89
748:2x 2x 11x 17
740:2x 2x 5x 37
225:3x 3x 5x 5
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 5x 11 = 220
Therefore, the value for common factors is 220.
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 = 121926618000/(1x220)
LCM = 121926618000/220
LCM = 554211900
Thus, we can understand that the LCM of 979,748,740,225 is 554211900.
