Given numbers are 685,959,851,834,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 685,959,851,834,402 is 228012693510.
Find LCM of 685,959,851,834,402 with Prime Factorization
| 2 | 685, 959, 851, 834, 402 |
| 3 | 685, 959, 851, 417, 201 |
| 137 | 685, 959, 851, 139, 67 |
| 5, 7, 851, 139, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 137 x 5 x 7 x 851 x 139 x 67 = 228012693510
Therefore, the lowest common multiple of 685,959,851,834,402 is 228012693510.
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.
685 x 959 x 851 x 834 x 402 = 187426434065220
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.
685 : 1, 5, 137, 685
959 : 1, 7, 137, 959
851 : 1, 23, 37, 851
834 : 1, 2, 3, 6, 139, 278, 417, 834
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,959,851,834,402, is 1.
Now, the common factors can be found like this.
685:5x 137
959:7x 137
851:23x 37
834:2x 3x 139
402:2x 3x 67
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 137 = 822
Therefore, the value for common factors is 822.
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 = 187426434065220/(1x822)
LCM = 187426434065220/822
LCM = 228012693510
Thus, we can understand that the LCM of 685,959,851,834,402 is 228012693510.
