Given numbers are 980,121,850,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,121,850,178 is 897057700.
Find LCM of 980,121,850,178 with Prime Factorization
| 2 | 980, 121, 850, 178 |
| 5 | 490, 121, 425, 89 |
| 98, 121, 85, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 98 x 121 x 85 x 89 = 897057700
Therefore, the lowest common multiple of 980,121,850,178 is 897057700.
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.
980 x 121 x 850 x 178 = 17941154000
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
121 : 1, 11, 121
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,121,850,178, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
121:11x 11
850:2x 5x 5x 17
178:2x 89
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 5 = 20
Therefore, the value for common factors is 20.
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 = 17941154000/(1x20)
LCM = 17941154000/20
LCM = 897057700
Thus, we can understand that the LCM of 980,121,850,178 is 897057700.
