Given numbers are 665,760,853,398
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 665,760,853,398 is 903054040.
Find LCM of 665,760,853,398 with Prime Factorization
2 | 665, 760, 853, 398 |
5 | 665, 380, 853, 199 |
19 | 133, 76, 853, 199 |
7, 4, 853, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 19 x 7 x 4 x 853 x 199 = 903054040
Therefore, the lowest common multiple of 665,760,853,398 is 903054040.
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.
665 x 760 x 853 x 398 = 171580267600
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.
665 : 1, 5, 7, 19, 35, 95, 133, 665
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
853 : 1, 853
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,760,853,398, is 1.
Now, the common factors can be found like this.
665:5x 7x 19
760:2x 2x 2x 5x 19
853:853
398:2x 199
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 19 = 190
Therefore, the value for common factors is 190.
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 = 171580267600/(1x190)
LCM = 171580267600/190
LCM = 903054040
Thus, we can understand that the LCM of 665,760,853,398 is 903054040.
