Find LCM of 760,394,440,940,691 with Prime Factorization
| 2 | 760, 394, 440, 940, 691 |
| 2 | 380, 197, 220, 470, 691 |
| 2 | 190, 197, 110, 235, 691 |
| 5 | 95, 197, 55, 235, 691 |
| 19, 197, 11, 47, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 19 x 197 x 11 x 47 x 691 = 53487020840
Therefore, the lowest common multiple of 760,394,440,940,691 is 53487020840.
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.
760 x 394 x 440 x 940 x 691 = 85579233344000
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
394 : 1, 2, 197, 394
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,394,440,940,691, is 1.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
394:2x 197
440:2x 2x 2x 5x 11
940:2x 2x 5x 47
691:691
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 2x 5x 5 = 1600
Therefore, the value for common factors is 1600.
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 = 85579233344000/(1x1600)
LCM = 85579233344000/1600
LCM = 53487020840
Thus, we can understand that the LCM of 760,394,440,940,691 is 53487020840.
