Given numbers are 642,726,247,532
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 642,726,247,532 is 268624356.
Find LCM of 642,726,247,532 with Prime Factorization
| 2 | 642, 726, 247, 532 |
| 3 | 321, 363, 247, 266 |
| 19 | 107, 121, 247, 266 |
| 107, 121, 13, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 107 x 121 x 13 x 14 = 268624356
Therefore, the lowest common multiple of 642,726,247,532 is 268624356.
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.
642 x 726 x 247 x 532 = 61246353168
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
247 : 1, 13, 19, 247
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,726,247,532, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
726:2x 3x 11x 11
247:13x 19
532:2x 2x 7x 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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 61246353168/(1x228)
LCM = 61246353168/228
LCM = 268624356
Thus, we can understand that the LCM of 642,726,247,532 is 268624356.
