The LCM of 821,616,348,532 is 835981608.
Find LCM of 821,616,348,532 with Prime Factorization
| 2 | 821, 616, 348, 532 |
| 2 | 821, 308, 174, 266 |
| 7 | 821, 154, 87, 133 |
| 821, 22, 87, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 821 x 22 x 87 x 19 = 835981608
Therefore, the lowest common multiple of 821,616,348,532 is 835981608.
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.
821 x 616 x 348 x 532 = 93629940096
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.
821 : 1, 821
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 821,616,348,532, is 1.
Now, the common factors can be found like this.
821:821
616:2x 2x 2x 7x 11
348:2x 2x 3x 29
532:2x 2x 7x 19
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 7 = 112
Therefore, the value for common factors is 112.
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 = 93629940096/(1x112)
LCM = 93629940096/112
LCM = 835981608
Thus, we can understand that the LCM of 821,616,348,532 is 835981608.
