Given numbers are 942,668,489,309,225
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,668,489,309,225 is 396171711900.
Find LCM of 942,668,489,309,225 with Prime Factorization
| 2 | 942, 668, 489, 309, 225 |
| 3 | 471, 334, 489, 309, 225 |
| 157, 334, 163, 103, 75 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 157 x 334 x 163 x 103 x 75 = 396171711900
Therefore, the lowest common multiple of 942,668,489,309,225 is 396171711900.
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.
942 x 668 x 489 x 309 x 225 = 21393272442600
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
668 : 1, 2, 4, 167, 334, 668
489 : 1, 3, 163, 489
309 : 1, 3, 103, 309
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,668,489,309,225, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
668:2x 2x 167
489:3x 163
309:3x 103
225:3x 3x 5x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 21393272442600/(1x54)
LCM = 21393272442600/54
LCM = 396171711900
Thus, we can understand that the LCM of 942,668,489,309,225 is 396171711900.
