The LCM of 529,820,420,390 is 118421940.
Find LCM of 529,820,420,390 with Prime Factorization
2 | 529, 820, 420, 390 |
2 | 529, 410, 210, 195 |
3 | 529, 205, 105, 195 |
5 | 529, 205, 35, 65 |
529, 41, 7, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 529 x 41 x 7 x 13 = 118421940
Therefore, the lowest common multiple of 529,820,420,390 is 118421940.
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.
529 x 820 x 420 x 390 = 71053164000
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.
529 : 1, 23, 529
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 529,820,420,390, is 1.
Now, the common factors can be found like this.
529:23x 23
820:2x 2x 5x 41
420:2x 2x 3x 5x 7
390:2x 3x 5x 13
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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 71053164000/(1x600)
LCM = 71053164000/600
LCM = 118421940
Thus, we can understand that the LCM of 529,820,420,390 is 118421940.
