Given numbers are 497,542,781,118
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 497,542,781,118 is 174823726.
Find LCM of 497,542,781,118 with Prime Factorization
| 2 | 497, 542, 781, 118 |
| 71 | 497, 271, 781, 59 |
| 7, 271, 11, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 7 x 271 x 11 x 59 = 174823726
Therefore, the lowest common multiple of 497,542,781,118 is 174823726.
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.
497 x 542 x 781 x 118 = 24824969092
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.
497 : 1, 7, 71, 497
542 : 1, 2, 271, 542
781 : 1, 11, 71, 781
118 : 1, 2, 59, 118
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 497,542,781,118, is 1.
Now, the common factors can be found like this.
497:7x 71
542:2x 271
781:11x 71
118:2x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71 = 142
Therefore, the value for common factors is 142.
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 = 24824969092/(1x142)
LCM = 24824969092/142
LCM = 174823726
Thus, we can understand that the LCM of 497,542,781,118 is 174823726.
