Find LCM of 784,583,680,253,991 with Prime Factorization
| 2 | 784, 583, 680, 253, 991 |
| 2 | 392, 583, 340, 253, 991 |
| 2 | 196, 583, 170, 253, 991 |
| 11 | 98, 583, 85, 253, 991 |
| 98, 53, 85, 23, 991 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 98 x 53 x 85 x 23 x 991 = 885533578160
Therefore, the lowest common multiple of 784,583,680,253,991 is 885533578160.
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.
784 x 583 x 680 x 253 x 991 = 77926954878080
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
583 : 1, 11, 53, 583
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
253 : 1, 11, 23, 253
991 : 1, 991
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,583,680,253,991, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
583:11x 53
680:2x 2x 2x 5x 17
253:11x 23
991:991
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 11 = 88
Therefore, the value for common factors is 88.
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 = 77926954878080/(1x88)
LCM = 77926954878080/88
LCM = 885533578160
Thus, we can understand that the LCM of 784,583,680,253,991 is 885533578160.
