Given numbers are 787,532,322,633,678
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 787,532,322,633,678 is 688805100228.
Find LCM of 787,532,322,633,678 with Prime Factorization
| 2 | 787, 532, 322, 633, 678 |
| 3 | 787, 266, 161, 633, 339 |
| 7 | 787, 266, 161, 211, 113 |
| 787, 38, 23, 211, 113 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 787 x 38 x 23 x 211 x 113 = 688805100228
Therefore, the lowest common multiple of 787,532,322,633,678 is 688805100228.
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 532 x 322 x 633 x 678 = 57859628419152
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
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
322 : 1, 2, 7, 14, 23, 46, 161, 322
633 : 1, 3, 211, 633
678 : 1, 2, 3, 6, 113, 226, 339, 678
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 787,532,322,633,678, is 1.
Now, the common factors can be found like this.
787:787
532:2x 2x 7x 19
322:2x 7x 23
633:3x 211
678:2x 3x 113
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 3x 7 = 84
Therefore, the value for common factors is 84.
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 = 57859628419152/(1x84)
LCM = 57859628419152/84
LCM = 688805100228
Thus, we can understand that the LCM of 787,532,322,633,678 is 688805100228.
