Find LCM of 778,512,484,224,221 with Prime Factorization
| 2 | 778, 512, 484, 224, 221 |
| 2 | 389, 256, 242, 112, 221 |
| 2 | 389, 128, 121, 56, 221 |
| 2 | 389, 64, 121, 28, 221 |
| 2 | 389, 32, 121, 14, 221 |
| 389, 16, 121, 7, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 389 x 16 x 121 x 7 x 221 = 37281660416
Therefore, the lowest common multiple of 778,512,484,224,221 is 37281660416.
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.
778 x 512 x 484 x 224 x 221 = 9544105066496
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.
778 : 1, 2, 389, 778
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
484 : 1, 2, 4, 11, 22, 44, 121, 242, 484
224 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, 224
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,512,484,224,221, is 1.
Now, the common factors can be found like this.
778:2x 389
512:2x 2x 2x 2x 2x 2x 2x 2x 2
484:2x 2x 11x 11
224:2x 2x 2x 2x 2x 7
221:13x 17
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 2x 2x 2x 2 = 256
Therefore, the value for common factors is 256.
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 = 9544105066496/(1x256)
LCM = 9544105066496/256
LCM = 37281660416
Thus, we can understand that the LCM of 778,512,484,224,221 is 37281660416.
