The LCM of 147,417,556,294 is 81732.
Find LCM of 147,417,556,294 with Prime Factorization
| 2 | 147, 417, 556, 294 |
| 3 | 147, 417, 278, 147 |
| 7 | 49, 139, 278, 49 |
| 7 | 7, 139, 278, 7 |
| 139 | 1, 139, 278, 1 |
| 1, 1, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 7 x 139 x 1 x 1 x 2 x 1 = 81732
Therefore, the lowest common multiple of 147,417,556,294 is 81732.
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.
147 x 417 x 556 x 294 = 10020179736
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.
147 : 1, 3, 7, 21, 49, 147
417 : 1, 3, 139, 417
556 : 1, 2, 4, 139, 278, 556
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 147,417,556,294, is 1.
Now, the common factors can be found like this.
147:3x 7x 7
417:3x 139
556:2x 2x 139
294:2x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7x 7x 139 = 122598
Therefore, the value for common factors is 122598.
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 = 10020179736/(1x122598)
LCM = 10020179736/122598
LCM = 81732
Thus, we can understand that the LCM of 147,417,556,294 is 81732.
