Find LCM of 688,590,989,665,340 with Prime Factorization
2 | 688, 590, 989, 665, 340 |
2 | 344, 295, 989, 665, 170 |
5 | 172, 295, 989, 665, 85 |
43 | 172, 59, 989, 133, 17 |
4, 59, 23, 133, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 4 x 59 x 23 x 133 x 17 = 10554528880
Therefore, the lowest common multiple of 688,590,989,665,340 is 10554528880.
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 590 x 989 x 665 x 340 = 90768948368000
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
590 : 1, 2, 5, 10, 59, 118, 295, 590
989 : 1, 23, 43, 989
665 : 1, 5, 7, 19, 35, 95, 133, 665
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,590,989,665,340, is 1.
Now, the common factors can be found like this.
688:2x 2x 2x 2x 43
590:2x 5x 59
989:23x 43
665:5x 7x 19
340:2x 2x 5x 17
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 2x 5x 5x 43 = 8600
Therefore, the value for common factors is 8600.
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 = 90768948368000/(1x8600)
LCM = 90768948368000/8600
LCM = 10554528880
Thus, we can understand that the LCM of 688,590,989,665,340 is 10554528880.
