Find LCM of 556,387,172,695,777 with Prime Factorization
| 2 | 556, 387, 172, 695, 777 |
| 2 | 278, 387, 86, 695, 777 |
| 3 | 139, 387, 43, 695, 777 |
| 43 | 139, 129, 43, 695, 259 |
| 139 | 139, 3, 1, 695, 259 |
| 1, 3, 1, 5, 259 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 139 x 1 x 3 x 1 x 5 x 259 = 278647740
Therefore, the lowest common multiple of 556,387,172,695,777 is 278647740.
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.
556 x 387 x 172 x 695 x 777 = 19985730503760
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.
556 : 1, 2, 4, 139, 278, 556
387 : 1, 3, 9, 43, 129, 387
172 : 1, 2, 4, 43, 86, 172
695 : 1, 5, 139, 695
777 : 1, 3, 7, 21, 37, 111, 259, 777
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,387,172,695,777, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
387:3x 3x 43
172:2x 2x 43
695:5x 139
777:3x 7x 37
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 3x 43x 139 = 71724
Therefore, the value for common factors is 71724.
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 = 19985730503760/(1x71724)
LCM = 19985730503760/71724
LCM = 278647740
Thus, we can understand that the LCM of 556,387,172,695,777 is 278647740.
