Given numbers are 980,987,690,716
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,987,690,716 is 568887060.
Find LCM of 980,987,690,716 with Prime Factorization
| 2 | 980, 987, 690, 716 |
| 2 | 490, 987, 345, 358 |
| 3 | 245, 987, 345, 179 |
| 5 | 245, 329, 115, 179 |
| 7 | 49, 329, 23, 179 |
| 7, 47, 23, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 7 x 47 x 23 x 179 = 568887060
Therefore, the lowest common multiple of 980,987,690,716 is 568887060.
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 987 x 690 x 716 = 477865130400
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
987 : 1, 3, 7, 21, 47, 141, 329, 987
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
716 : 1, 2, 4, 179, 358, 716
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,987,690,716, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
987:3x 7x 47
690:2x 3x 5x 23
716:2x 2x 179
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 3x 5x 7 = 840
Therefore, the value for common factors is 840.
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 = 477865130400/(1x840)
LCM = 477865130400/840
LCM = 568887060
Thus, we can understand that the LCM of 980,987,690,716 is 568887060.
