Find LCM of 397,426,711,880,715 with Prime Factorization
2 | 397, 426, 711, 880, 715 |
3 | 397, 213, 711, 440, 715 |
5 | 397, 71, 237, 440, 715 |
11 | 397, 71, 237, 88, 143 |
397, 71, 237, 8, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 397 x 71 x 237 x 8 x 13 = 229268548080
Therefore, the lowest common multiple of 397,426,711,880,715 is 229268548080.
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.
397 x 426 x 711 x 880 x 715 = 75658620866400
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.
397 : 1, 397
426 : 1, 2, 3, 6, 71, 142, 213, 426
711 : 1, 3, 9, 79, 237, 711
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 397,426,711,880,715, is 1.
Now, the common factors can be found like this.
397:397
426:2x 3x 71
711:3x 3x 79
880:2x 2x 2x 2x 5x 11
715:5x 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 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 75658620866400/(1x330)
LCM = 75658620866400/330
LCM = 229268548080
Thus, we can understand that the LCM of 397,426,711,880,715 is 229268548080.
