Given numbers are 668,298,961,683,560
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,298,961,683,560 is 9146077096240.
Find LCM of 668,298,961,683,560 with Prime Factorization
| 2 | 668, 298, 961, 683, 560 |
| 2 | 334, 149, 961, 683, 280 |
| 167, 149, 961, 683, 140 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 167 x 149 x 961 x 683 x 140 = 9146077096240
Therefore, the lowest common multiple of 668,298,961,683,560 is 9146077096240.
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.
668 x 298 x 961 x 683 x 560 = 73168616769920
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.
668 : 1, 2, 4, 167, 334, 668
298 : 1, 2, 149, 298
961 : 1, 31, 961
683 : 1, 683
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,298,961,683,560, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
298:2x 149
961:31x 31
683:683
560:2x 2x 2x 2x 5x 7
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 2 = 8
Therefore, the value for common factors is 8.
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 = 73168616769920/(1x8)
LCM = 73168616769920/8
LCM = 9146077096240
Thus, we can understand that the LCM of 668,298,961,683,560 is 9146077096240.
