Given numbers are 747,646,838,752,152
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,646,838,752,152 is 76024747728.
Find LCM of 747,646,838,752,152 with Prime Factorization
| 2 | 747, 646, 838, 752, 152 |
| 2 | 747, 323, 419, 376, 76 |
| 2 | 747, 323, 419, 188, 38 |
| 19 | 747, 323, 419, 94, 19 |
| 747, 17, 419, 94, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 19 x 747 x 17 x 419 x 94 x 1 = 76024747728
Therefore, the lowest common multiple of 747,646,838,752,152 is 76024747728.
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.
747 x 646 x 838 x 752 x 152 = 46223046618624
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.
747 : 1, 3, 9, 83, 249, 747
646 : 1, 2, 17, 19, 34, 38, 323, 646
838 : 1, 2, 419, 838
752 : 1, 2, 4, 8, 16, 47, 94, 188, 376, 752
152 : 1, 2, 4, 8, 19, 38, 76, 152
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,646,838,752,152, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
646:2x 17x 19
838:2x 419
752:2x 2x 2x 2x 47
152:2x 2x 2x 19
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 19 = 608
Therefore, the value for common factors is 608.
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 = 46223046618624/(1x608)
LCM = 46223046618624/608
LCM = 76024747728
Thus, we can understand that the LCM of 747,646,838,752,152 is 76024747728.
