Find LCM of 644,759,947,836,767 with Prime Factorization
| 2 | 644, 759, 947, 836, 767 |
| 2 | 322, 759, 947, 418, 767 |
| 11 | 161, 759, 947, 209, 767 |
| 23 | 161, 69, 947, 19, 767 |
| 7, 3, 947, 19, 767 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 23 x 7 x 3 x 947 x 19 x 767 = 293291010012
Therefore, the lowest common multiple of 644,759,947,836,767 is 293291010012.
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.
644 x 759 x 947 x 836 x 767 = 296810502132144
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.
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
759 : 1, 3, 11, 23, 33, 69, 253, 759
947 : 1, 947
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 644,759,947,836,767, is 1.
Now, the common factors can be found like this.
644:2x 2x 7x 23
759:3x 11x 23
947:947
836:2x 2x 11x 19
767:13x 59
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 11x 23 = 1012
Therefore, the value for common factors is 1012.
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 = 296810502132144/(1x1012)
LCM = 296810502132144/1012
LCM = 293291010012
Thus, we can understand that the LCM of 644,759,947,836,767 is 293291010012.
