Find LCM of 669,395,784,136,532 with Prime Factorization
| 2 | 669, 395, 784, 136, 532 |
| 2 | 669, 395, 392, 68, 266 |
| 2 | 669, 395, 196, 34, 133 |
| 7 | 669, 395, 98, 17, 133 |
| 669, 395, 14, 17, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 669 x 395 x 14 x 17 x 19 = 66917822160
Therefore, the lowest common multiple of 669,395,784,136,532 is 66917822160.
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.
669 x 395 x 784 x 136 x 532 = 14989592163840
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.
669 : 1, 3, 223, 669
395 : 1, 5, 79, 395
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
136 : 1, 2, 4, 8, 17, 34, 68, 136
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 669,395,784,136,532, is 1.
Now, the common factors can be found like this.
669:3x 223
395:5x 79
784:2x 2x 2x 2x 7x 7
136:2x 2x 2x 17
532:2x 2x 7x 19
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 7 = 224
Therefore, the value for common factors is 224.
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 = 14989592163840/(1x224)
LCM = 14989592163840/224
LCM = 66917822160
Thus, we can understand that the LCM of 669,395,784,136,532 is 66917822160.
