Given numbers are 697,861,469,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,861,469,754 is 739431966.
Find LCM of 697,861,469,754 with Prime Factorization
| 7 | 697, 861, 469, 754 |
| 41 | 697, 123, 67, 754 |
| 17, 3, 67, 754 |
Multiply the prime numbers at the bottom and the left side.
7 x 41 x 17 x 3 x 67 x 754 = 739431966
Therefore, the lowest common multiple of 697,861,469,754 is 739431966.
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 861 x 469 x 754 = 212216974242
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
861 : 1, 3, 7, 21, 41, 123, 287, 861
469 : 1, 7, 67, 469
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,861,469,754, is 1.
Now, the common factors can be found like this.
697:17x 41
861:3x 7x 41
469:7x 67
754:2x 13x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 41 = 287
Therefore, the value for common factors is 287.
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 = 212216974242/(1x287)
LCM = 212216974242/287
LCM = 739431966
Thus, we can understand that the LCM of 697,861,469,754 is 739431966.
