Given numbers are 980,989,308,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,989,308,572 is 138598460.
Find LCM of 980,989,308,572 with Prime Factorization
| 2 | 980, 989, 308, 572 |
| 2 | 490, 989, 154, 286 |
| 7 | 245, 989, 77, 143 |
| 11 | 35, 989, 11, 143 |
| 35, 989, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 35 x 989 x 1 x 13 = 138598460
Therefore, the lowest common multiple of 980,989,308,572 is 138598460.
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 989 x 308 x 572 = 170753302720
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
989 : 1, 23, 43, 989
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,989,308,572, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
989:23x 43
308:2x 2x 7x 11
572:2x 2x 11x 13
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 2x 7x 11 = 1232
Therefore, the value for common factors is 1232.
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 = 170753302720/(1x1232)
LCM = 170753302720/1232
LCM = 138598460
Thus, we can understand that the LCM of 980,989,308,572 is 138598460.
