Given numbers are 272,638,118,578,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 272,638,118,578,545 is 47430425680.
Find LCM of 272,638,118,578,545 with Prime Factorization
| 2 | 272, 638, 118, 578, 545 |
| 17 | 136, 319, 59, 289, 545 |
| 8, 319, 59, 17, 545 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 8 x 319 x 59 x 17 x 545 = 47430425680
Therefore, the lowest common multiple of 272,638,118,578,545 is 47430425680.
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.
272 x 638 x 118 x 578 x 545 = 6450537892480
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
638 : 1, 2, 11, 22, 29, 58, 319, 638
118 : 1, 2, 59, 118
578 : 1, 2, 17, 34, 289, 578
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,638,118,578,545, is 1.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
638:2x 11x 29
118:2x 59
578:2x 17x 17
545:5x 109
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 17 = 136
Therefore, the value for common factors is 136.
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 = 6450537892480/(1x136)
LCM = 6450537892480/136
LCM = 47430425680
Thus, we can understand that the LCM of 272,638,118,578,545 is 47430425680.
