Find LCM of 812,960,861,269,980 with Prime Factorization
2 | 812, 960, 861, 269, 980 |
2 | 406, 480, 861, 269, 490 |
3 | 203, 240, 861, 269, 245 |
5 | 203, 80, 287, 269, 245 |
7 | 203, 16, 287, 269, 49 |
29, 16, 41, 269, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 29 x 16 x 41 x 269 x 7 = 15045320640
Therefore, the lowest common multiple of 812,960,861,269,980 is 15045320640.
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.
812 x 960 x 861 x 269 x 980 = 176932970726400
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.
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
861 : 1, 3, 7, 21, 41, 123, 287, 861
269 : 1, 269
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 812,960,861,269,980, is 1.
Now, the common factors can be found like this.
812:2x 2x 7x 29
960:2x 2x 2x 2x 2x 2x 3x 5
861:3x 7x 41
269:269
980:2x 2x 5x 7x 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 2x 3x 5x 7x 7 = 11760
Therefore, the value for common factors is 11760.
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 = 176932970726400/(1x11760)
LCM = 176932970726400/11760
LCM = 15045320640
Thus, we can understand that the LCM of 812,960,861,269,980 is 15045320640.
