The LCM of 697,686,490,529,974 is 615901882330.
Find LCM of 697,686,490,529,974 with Prime Factorization
| 2 | 697, 686, 490, 529, 974 |
| 7 | 697, 343, 245, 529, 487 |
| 7 | 697, 49, 35, 529, 487 |
| 697, 7, 5, 529, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 697 x 7 x 5 x 529 x 487 = 615901882330
Therefore, the lowest common multiple of 697,686,490,529,974 is 615901882330.
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 686 x 490 x 529 x 974 = 120716768936680
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
686 : 1, 2, 7, 14, 49, 98, 343, 686
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
529 : 1, 23, 529
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,686,490,529,974, is 1.
Now, the common factors can be found like this.
697:17x 41
686:2x 7x 7x 7
490:2x 5x 7x 7
529:23x 23
974:2x 487
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 7x 7 = 196
Therefore, the value for common factors is 196.
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 = 120716768936680/(1x196)
LCM = 120716768936680/196
LCM = 615901882330
Thus, we can understand that the LCM of 697,686,490,529,974 is 615901882330.
