Given numbers are 651,655,253,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 651,655,253,685 is 14779623705.
Find LCM of 651,655,253,685 with Prime Factorization
| 5 | 651, 655, 253, 685 |
| 651, 131, 253, 137 |
Multiply the prime numbers at the bottom and the left side.
5 x 651 x 131 x 253 x 137 = 14779623705
Therefore, the lowest common multiple of 651,655,253,685 is 14779623705.
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.
651 x 655 x 253 x 685 = 73898118525
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
655 : 1, 5, 131, 655
253 : 1, 11, 23, 253
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,655,253,685, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
655:5x 131
253:11x 23
685:5x 137
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 73898118525/(1x5)
LCM = 73898118525/5
LCM = 14779623705
Thus, we can understand that the LCM of 651,655,253,685 is 14779623705.
