The LCM of 185,655,880,840 is 89572560.
Find LCM of 185,655,880,840 with Prime Factorization
2 | 185, 655, 880, 840 |
2 | 185, 655, 440, 420 |
2 | 185, 655, 220, 210 |
5 | 185, 655, 110, 105 |
37, 131, 22, 21 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 37 x 131 x 22 x 21 = 89572560
Therefore, the lowest common multiple of 185,655,880,840 is 89572560.
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.
185 x 655 x 880 x 840 = 89572560000
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.
185 : 1, 5, 37, 185
655 : 1, 5, 131, 655
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 185,655,880,840, is 5.
Now, the common factors can be found like this.
185:5x 37
655:5x 131
880:2x 2x 2x 2x 5x 11
840:2x 2x 2x 3x 5x 7
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 5 = 200
Therefore, the value for common factors is 200.
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 = 89572560000/(5x200)
LCM = 89572560000/1000
LCM = 89572560
Thus, we can understand that the LCM of 185,655,880,840 is 89572560.
