Find LCM of 742,852,889,195,780 with Prime Factorization
| 2 | 742, 852, 889, 195, 780 |
| 2 | 371, 426, 889, 195, 390 |
| 3 | 371, 213, 889, 195, 195 |
| 5 | 371, 71, 889, 65, 65 |
| 7 | 371, 71, 889, 13, 13 |
| 13 | 53, 71, 127, 13, 13 |
| 53, 71, 127, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 13 x 53 x 71 x 127 x 1 x 1 = 2609339460
Therefore, the lowest common multiple of 742,852,889,195,780 is 2609339460.
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 852 x 889 x 195 x 780 = 85481960709600
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
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
889 : 1, 7, 127, 889
195 : 1, 3, 5, 13, 15, 39, 65, 195
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 742,852,889,195,780, is 1.
Now, the common factors can be found like this.
742:2x 7x 53
852:2x 2x 3x 71
889:7x 127
195:3x 5x 13
780:2x 2x 3x 5x 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 3x 5x 7x 13 = 32760
Therefore, the value for common factors is 32760.
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 = 85481960709600/(1x32760)
LCM = 85481960709600/32760
LCM = 2609339460
Thus, we can understand that the LCM of 742,852,889,195,780 is 2609339460.
