Given numbers are 545,920,746,674,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 545,920,746,674,172 is 542027740040.
Find LCM of 545,920,746,674,172 with Prime Factorization
| 2 | 545, 920, 746, 674, 172 |
| 2 | 545, 460, 373, 337, 86 |
| 5 | 545, 230, 373, 337, 43 |
| 109, 46, 373, 337, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 109 x 46 x 373 x 337 x 43 = 542027740040
Therefore, the lowest common multiple of 545,920,746,674,172 is 542027740040.
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.
545 x 920 x 746 x 674 x 172 = 43362219203200
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.
545 : 1, 5, 109, 545
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
746 : 1, 2, 373, 746
674 : 1, 2, 337, 674
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,920,746,674,172, is 1.
Now, the common factors can be found like this.
545:5x 109
920:2x 2x 2x 5x 23
746:2x 373
674:2x 337
172:2x 2x 43
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 5 = 80
Therefore, the value for common factors is 80.
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 = 43362219203200/(1x80)
LCM = 43362219203200/80
LCM = 542027740040
Thus, we can understand that the LCM of 545,920,746,674,172 is 542027740040.
