Find LCM of 689,510,680,863,690 with Prime Factorization
2 | 689, 510, 680, 863, 690 |
3 | 689, 255, 340, 863, 345 |
5 | 689, 85, 340, 863, 115 |
17 | 689, 17, 68, 863, 23 |
689, 1, 4, 863, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 689 x 1 x 4 x 863 x 23 = 27898960440
Therefore, the lowest common multiple of 689,510,680,863,690 is 27898960440.
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.
689 x 510 x 680 x 863 x 690 = 142284698244000
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.
689 : 1, 13, 53, 689
510 : 1, 2, 3, 5, 6, 10, 15, 17, 30, 34, 51, 85, 102, 170, 255, 510
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
863 : 1, 863
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,510,680,863,690, is 1.
Now, the common factors can be found like this.
689:13x 53
510:2x 3x 5x 17
680:2x 2x 2x 5x 17
863:863
690:2x 3x 5x 23
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 3x 5x 5x 17 = 5100
Therefore, the value for common factors is 5100.
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 = 142284698244000/(1x5100)
LCM = 142284698244000/5100
LCM = 27898960440
Thus, we can understand that the LCM of 689,510,680,863,690 is 27898960440.
