Given numbers are 453,625,817,123,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,625,817,123,138 is 436256553750.
Find LCM of 453,625,817,123,138 with Prime Factorization
| 3 | 453, 625, 817, 123, 138 |
| 151, 625, 817, 41, 46 |
Multiply the prime numbers at the bottom and the left side.
3 x 151 x 625 x 817 x 41 x 46 = 436256553750
Therefore, the lowest common multiple of 453,625,817,123,138 is 436256553750.
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.
453 x 625 x 817 x 123 x 138 = 3926308983750
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.
453 : 1, 3, 151, 453
625 : 1, 5, 25, 125, 625
817 : 1, 19, 43, 817
123 : 1, 3, 41, 123
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,625,817,123,138, is 1.
Now, the common factors can be found like this.
453:3x 151
625:5x 5x 5x 5
817:19x 43
123:3x 41
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 3926308983750/(1x9)
LCM = 3926308983750/9
LCM = 436256553750
Thus, we can understand that the LCM of 453,625,817,123,138 is 436256553750.
