Find LCM of 691,152,944,874,761 with Prime Factorization
| 2 | 691, 152, 944, 874, 761 |
| 2 | 691, 76, 472, 437, 761 |
| 2 | 691, 38, 236, 437, 761 |
| 19 | 691, 19, 118, 437, 761 |
| 691, 1, 118, 23, 761 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 691 x 1 x 118 x 23 x 761 = 216928261328
Therefore, the lowest common multiple of 691,152,944,874,761 is 216928261328.
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.
691 x 152 x 944 x 874 x 761 = 65946191443712
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.
691 : 1, 691
152 : 1, 2, 4, 8, 19, 38, 76, 152
944 : 1, 2, 4, 8, 16, 59, 118, 236, 472, 944
874 : 1, 2, 19, 23, 38, 46, 437, 874
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 691,152,944,874,761, is 1.
Now, the common factors can be found like this.
691:691
152:2x 2x 2x 19
944:2x 2x 2x 2x 59
874:2x 19x 23
761:761
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 19 = 304
Therefore, the value for common factors is 304.
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 = 65946191443712/(1x304)
LCM = 65946191443712/304
LCM = 216928261328
Thus, we can understand that the LCM of 691,152,944,874,761 is 216928261328.
