Given numbers are 692,697,655,508
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 692,697,655,508 is 40122121940.
Find LCM of 692,697,655,508 with Prime Factorization
| 2 | 692, 697, 655, 508 |
| 2 | 346, 697, 655, 254 |
| 173, 697, 655, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 173 x 697 x 655 x 127 = 40122121940
Therefore, the lowest common multiple of 692,697,655,508 is 40122121940.
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.
692 x 697 x 655 x 508 = 160488487760
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.
692 : 1, 2, 4, 173, 346, 692
697 : 1, 17, 41, 697
655 : 1, 5, 131, 655
508 : 1, 2, 4, 127, 254, 508
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,697,655,508, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
697:17x 41
655:5x 131
508:2x 2x 127
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 160488487760/(1x4)
LCM = 160488487760/4
LCM = 40122121940
Thus, we can understand that the LCM of 692,697,655,508 is 40122121940.
