Given numbers are 989,294,685,668,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 989,294,685,668,685 is 66524353140.
Find LCM of 989,294,685,668,685 with Prime Factorization
| 2 | 989, 294, 685, 668, 685 |
| 5 | 989, 147, 685, 334, 685 |
| 137 | 989, 147, 137, 334, 137 |
| 989, 147, 1, 334, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 137 x 989 x 147 x 1 x 334 x 1 = 66524353140
Therefore, the lowest common multiple of 989,294,685,668,685 is 66524353140.
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.
989 x 294 x 685 x 668 x 685 = 91138363801800
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.
989 : 1, 23, 43, 989
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
685 : 1, 5, 137, 685
668 : 1, 2, 4, 167, 334, 668
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 989,294,685,668,685, is 1.
Now, the common factors can be found like this.
989:23x 43
294:2x 3x 7x 7
685:5x 137
668:2x 2x 167
685:5x 137
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 137 = 1370
Therefore, the value for common factors is 1370.
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 = 91138363801800/(1x1370)
LCM = 91138363801800/1370
LCM = 66524353140
Thus, we can understand that the LCM of 989,294,685,668,685 is 66524353140.
