Given numbers are 688,274,722,318
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,274,722,318 is 5410200144.
Find LCM of 688,274,722,318 with Prime Factorization
| 2 | 688, 274, 722, 318 |
| 344, 137, 361, 159 |
Multiply the prime numbers at the bottom and the left side.
2 x 344 x 137 x 361 x 159 = 5410200144
Therefore, the lowest common multiple of 688,274,722,318 is 5410200144.
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.
688 x 274 x 722 x 318 = 43281601152
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.
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
274 : 1, 2, 137, 274
722 : 1, 2, 19, 38, 361, 722
318 : 1, 2, 3, 6, 53, 106, 159, 318
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,274,722,318, is 2.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
274:2x 137
722:2x 19x 19
318:2x 3x 53
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 = 43281601152/(2x4)
LCM = 43281601152/8
LCM = 5410200144
Thus, we can understand that the LCM of 688,274,722,318 is 5410200144.
