Given numbers are 988,298,640,398,567
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 988,298,640,398,567 is 2657659455360.
Find LCM of 988,298,640,398,567 with Prime Factorization
| 2 | 988, 298, 640, 398, 567 |
| 2 | 494, 149, 320, 199, 567 |
| 247, 149, 160, 199, 567 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 247 x 149 x 160 x 199 x 567 = 2657659455360
Therefore, the lowest common multiple of 988,298,640,398,567 is 2657659455360.
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.
988 x 298 x 640 x 398 x 567 = 42522551285760
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.
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
298 : 1, 2, 149, 298
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
398 : 1, 2, 199, 398
567 : 1, 3, 7, 9, 21, 27, 63, 81, 189, 567
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 988,298,640,398,567, is 1.
Now, the common factors can be found like this.
988:2x 2x 13x 19
298:2x 149
640:2x 2x 2x 2x 2x 2x 2x 5
398:2x 199
567:3x 3x 3x 3x 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 2x 2 = 16
Therefore, the value for common factors is 16.
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 = 42522551285760/(1x16)
LCM = 42522551285760/16
LCM = 2657659455360
Thus, we can understand that the LCM of 988,298,640,398,567 is 2657659455360.
