Find LCM of 874,457,690,680,985 with Prime Factorization
2 | 874, 457, 690, 680, 985 |
5 | 437, 457, 345, 340, 985 |
23 | 437, 457, 69, 68, 197 |
19, 457, 3, 68, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 19 x 457 x 3 x 68 x 197 = 80259052920
Therefore, the lowest common multiple of 874,457,690,680,985 is 80259052920.
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.
874 x 457 x 690 x 680 x 985 = 184595821716000
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.
874 : 1, 2, 19, 23, 38, 46, 437, 874
457 : 1, 457
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
985 : 1, 5, 197, 985
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,457,690,680,985, is 1.
Now, the common factors can be found like this.
874:2x 19x 23
457:457
690:2x 3x 5x 23
680:2x 2x 2x 5x 17
985:5x 197
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 5x 5x 23 = 2300
Therefore, the value for common factors is 2300.
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 = 184595821716000/(1x2300)
LCM = 184595821716000/2300
LCM = 80259052920
Thus, we can understand that the LCM of 874,457,690,680,985 is 80259052920.
