The LCM of 891,253,494,708,947 is 1131265324332.
Find LCM of 891,253,494,708,947 with Prime Factorization
| 2 | 891, 253, 494, 708, 947 |
| 3 | 891, 253, 247, 354, 947 |
| 11 | 297, 253, 247, 118, 947 |
| 27, 23, 247, 118, 947 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 27 x 23 x 247 x 118 x 947 = 1131265324332
Therefore, the lowest common multiple of 891,253,494,708,947 is 1131265324332.
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.
891 x 253 x 494 x 708 x 947 = 74663511405912
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
253 : 1, 11, 23, 253
494 : 1, 2, 13, 19, 26, 38, 247, 494
708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,253,494,708,947, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
253:11x 23
494:2x 13x 19
708:2x 2x 3x 59
947:947
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 11 = 66
Therefore, the value for common factors is 66.
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 = 74663511405912/(1x66)
LCM = 74663511405912/66
LCM = 1131265324332
Thus, we can understand that the LCM of 891,253,494,708,947 is 1131265324332.
