Given numbers are 781,697,173,869,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 781,697,173,869,634 is 4716786993446.
Find LCM of 781,697,173,869,634 with Prime Factorization
| 11 | 781, 697, 173, 869, 634 |
| 71, 697, 173, 79, 634 |
Multiply the prime numbers at the bottom and the left side.
11 x 71 x 697 x 173 x 79 x 634 = 4716786993446
Therefore, the lowest common multiple of 781,697,173,869,634 is 4716786993446.
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.
781 x 697 x 173 x 869 x 634 = 51884656927906
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.
781 : 1, 11, 71, 781
697 : 1, 17, 41, 697
173 : 1, 173
869 : 1, 11, 79, 869
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 781,697,173,869,634, is 1.
Now, the common factors can be found like this.
781:11x 71
697:17x 41
173:173
869:11x 79
634:2x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11 = 11
Therefore, the value for common factors is 11.
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 = 51884656927906/(1x11)
LCM = 51884656927906/11
LCM = 4716786993446
Thus, we can understand that the LCM of 781,697,173,869,634 is 4716786993446.
