Find LCM of 740,962,551,731,420 with Prime Factorization
| 2 | 740, 962, 551, 731, 420 |
| 2 | 370, 481, 551, 731, 210 |
| 5 | 185, 481, 551, 731, 105 |
| 37 | 37, 481, 551, 731, 21 |
| 1, 13, 551, 731, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 37 x 1 x 13 x 551 x 731 x 21 = 81369817620
Therefore, the lowest common multiple of 740,962,551,731,420 is 81369817620.
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.
740 x 962 x 551 x 731 x 420 = 120427330077600
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.
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
962 : 1, 2, 13, 26, 37, 74, 481, 962
551 : 1, 19, 29, 551
731 : 1, 17, 43, 731
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,962,551,731,420, is 1.
Now, the common factors can be found like this.
740:2x 2x 5x 37
962:2x 13x 37
551:19x 29
731:17x 43
420:2x 2x 3x 5x 7
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 5x 37 = 1480
Therefore, the value for common factors is 1480.
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 = 120427330077600/(1x1480)
LCM = 120427330077600/1480
LCM = 81369817620
Thus, we can understand that the LCM of 740,962,551,731,420 is 81369817620.
