Given numbers are 980,841,445,245
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,841,445,245 is 73352020.
Find LCM of 980,841,445,245 with Prime Factorization
| 5 | 980, 841, 445, 245 |
| 7 | 196, 841, 89, 49 |
| 7 | 28, 841, 89, 7 |
| 4, 841, 89, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 7 x 4 x 841 x 89 x 1 = 73352020
Therefore, the lowest common multiple of 980,841,445,245 is 73352020.
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 841 x 445 x 245 = 89856224500
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
841 : 1, 29, 841
445 : 1, 5, 89, 445
245 : 1, 5, 7, 35, 49, 245
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,841,445,245, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
841:29x 29
445:5x 89
245:5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7x 7 = 1225
Therefore, the value for common factors is 1225.
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 = 89856224500/(1x1225)
LCM = 89856224500/1225
LCM = 73352020
Thus, we can understand that the LCM of 980,841,445,245 is 73352020.
