Given numbers are 492,278,455,655,518
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 492,278,455,655,518 is 150821869380.
Find LCM of 492,278,455,655,518 with Prime Factorization
| 2 | 492, 278, 455, 655, 518 |
| 5 | 246, 139, 455, 655, 259 |
| 7 | 246, 139, 91, 131, 259 |
| 246, 139, 13, 131, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 246 x 139 x 13 x 131 x 37 = 150821869380
Therefore, the lowest common multiple of 492,278,455,655,518 is 150821869380.
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.
492 x 278 x 455 x 655 x 518 = 21115061713200
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.
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
278 : 1, 2, 139, 278
455 : 1, 5, 7, 13, 35, 65, 91, 455
655 : 1, 5, 131, 655
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 492,278,455,655,518, is 1.
Now, the common factors can be found like this.
492:2x 2x 3x 41
278:2x 139
455:5x 7x 13
655:5x 131
518:2x 7x 37
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 21115061713200/(1x140)
LCM = 21115061713200/140
LCM = 150821869380
Thus, we can understand that the LCM of 492,278,455,655,518 is 150821869380.
