Given numbers are 142,508,280,693,102
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,508,280,693,102 is 4249171080.
Find LCM of 142,508,280,693,102 with Prime Factorization
| 2 | 142, 508, 280, 693, 102 |
| 2 | 71, 254, 140, 693, 51 |
| 3 | 71, 127, 70, 693, 51 |
| 7 | 71, 127, 70, 231, 17 |
| 71, 127, 10, 33, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 71 x 127 x 10 x 33 x 17 = 4249171080
Therefore, the lowest common multiple of 142,508,280,693,102 is 4249171080.
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.
142 x 508 x 280 x 693 x 102 = 1427721482880
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.
142 : 1, 2, 71, 142
508 : 1, 2, 4, 127, 254, 508
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
102 : 1, 2, 3, 6, 17, 34, 51, 102
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,508,280,693,102, is 1.
Now, the common factors can be found like this.
142:2x 71
508:2x 2x 127
280:2x 2x 2x 5x 7
693:3x 3x 7x 11
102:2x 3x 17
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 2x 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 1427721482880/(1x336)
LCM = 1427721482880/336
LCM = 4249171080
Thus, we can understand that the LCM of 142,508,280,693,102 is 4249171080.
