Find LCM of 742,561,804,238,910 with Prime Factorization
| 2 | 742, 561, 804, 238, 910 |
| 3 | 371, 561, 402, 119, 455 |
| 7 | 371, 187, 134, 119, 455 |
| 17 | 53, 187, 134, 17, 65 |
| 53, 11, 134, 1, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 53 x 11 x 134 x 1 x 65 = 3625642020
Therefore, the lowest common multiple of 742,561,804,238,910 is 3625642020.
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.
742 x 561 x 804 x 238 x 910 = 72483835263840
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.
742 : 1, 2, 7, 14, 53, 106, 371, 742
561 : 1, 3, 11, 17, 33, 51, 187, 561
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
238 : 1, 2, 7, 14, 17, 34, 119, 238
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,561,804,238,910, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
561:3x 11x 17
804:2x 2x 3x 67
238:2x 7x 17
910:2x 5x 7x 13
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 3x 7x 7x 17 = 19992
Therefore, the value for common factors is 19992.
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 = 72483835263840/(1x19992)
LCM = 72483835263840/19992
LCM = 3625642020
Thus, we can understand that the LCM of 742,561,804,238,910 is 3625642020.
