Given numbers are 697,634,896,634,787
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,634,896,634,787 is 155802629248.
Find LCM of 697,634,896,634,787 with Prime Factorization
| 2 | 697, 634, 896, 634, 787 |
| 317 | 697, 317, 448, 317, 787 |
| 697, 1, 448, 1, 787 |
Multiply the prime numbers at the bottom and the left side.
2 x 317 x 697 x 1 x 448 x 1 x 787 = 155802629248
Therefore, the lowest common multiple of 697,634,896,634,787 is 155802629248.
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.
697 x 634 x 896 x 634 x 787 = 197557733886464
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.
697 : 1, 17, 41, 697
634 : 1, 2, 317, 634
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
634 : 1, 2, 317, 634
787 : 1, 787
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,634,896,634,787, is 1.
Now, the common factors can be found like this.
697:17x 41
634:2x 317
896:2x 2x 2x 2x 2x 2x 2x 7
634:2x 317
787:787
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 317 = 1268
Therefore, the value for common factors is 1268.
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 = 197557733886464/(1x1268)
LCM = 197557733886464/1268
LCM = 155802629248
Thus, we can understand that the LCM of 697,634,896,634,787 is 155802629248.
