Find LCM of 787,261,991,336,432 with Prime Factorization
2 | 787, 261, 991, 336, 432 |
2 | 787, 261, 991, 168, 216 |
2 | 787, 261, 991, 84, 108 |
2 | 787, 261, 991, 42, 54 |
3 | 787, 261, 991, 21, 27 |
3 | 787, 87, 991, 7, 9 |
787, 29, 991, 7, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 787 x 29 x 991 x 7 x 3 = 68395601232
Therefore, the lowest common multiple of 787,261,991,336,432 is 68395601232.
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.
787 x 261 x 991 x 336 x 432 = 29546899732224
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.
787 : 1, 787
261 : 1, 3, 9, 29, 87, 261
991 : 1, 991
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,261,991,336,432, is 1.
Now, the common factors can be found like this.
787:787
261:3x 3x 29
991:991
336:2x 2x 2x 2x 3x 7
432:2x 2x 2x 2x 3x 3x 3
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 2x 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 29546899732224/(1x432)
LCM = 29546899732224/432
LCM = 68395601232
Thus, we can understand that the LCM of 787,261,991,336,432 is 68395601232.
