Given numbers are 502,971,105,980,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 502,971,105,980,161 is 16480414020.
Find LCM of 502,971,105,980,161 with Prime Factorization
| 2 | 502, 971, 105, 980, 161 |
| 5 | 251, 971, 105, 490, 161 |
| 7 | 251, 971, 21, 98, 161 |
| 251, 971, 3, 14, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 251 x 971 x 3 x 14 x 23 = 16480414020
Therefore, the lowest common multiple of 502,971,105,980,161 is 16480414020.
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.
502 x 971 x 105 x 980 x 161 = 8075402869800
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.
502 : 1, 2, 251, 502
971 : 1, 971
105 : 1, 3, 5, 7, 15, 21, 35, 105
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,971,105,980,161, is 1.
Now, the common factors can be found like this.
502:2x 251
971:971
105:3x 5x 7
980:2x 2x 5x 7x 7
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7x 7 = 490
Therefore, the value for common factors is 490.
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 = 8075402869800/(1x490)
LCM = 8075402869800/490
LCM = 16480414020
Thus, we can understand that the LCM of 502,971,105,980,161 is 16480414020.
