Given numbers are 688,554,611,153
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 688,554,611,153 is 17815616208.
Find LCM of 688,554,611,153 with Prime Factorization
| 2 | 688, 554, 611, 153 |
| 344, 277, 611, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 344 x 277 x 611 x 153 = 17815616208
Therefore, the lowest common multiple of 688,554,611,153 is 17815616208.
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 554 x 611 x 153 = 35631232416
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
554 : 1, 2, 277, 554
611 : 1, 13, 47, 611
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,554,611,153, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
554:2x 277
611:13x 47
153:3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 35631232416/(1x2)
LCM = 35631232416/2
LCM = 17815616208
Thus, we can understand that the LCM of 688,554,611,153 is 17815616208.
