The LCM of 361,972,786,532 is 321767964.
Find LCM of 361,972,786,532 with Prime Factorization
| 2 | 361, 972, 786, 532 |
| 2 | 361, 486, 393, 266 |
| 3 | 361, 243, 393, 133 |
| 19 | 361, 81, 131, 133 |
| 19, 81, 131, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 19 x 81 x 131 x 7 = 321767964
Therefore, the lowest common multiple of 361,972,786,532 is 321767964.
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.
361 x 972 x 786 x 532 = 146726191584
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.
361 : 1, 19, 361
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
786 : 1, 2, 3, 6, 131, 262, 393, 786
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 361,972,786,532, is 1.
Now, the common factors can be found like this.
361:19x 19
972:2x 2x 3x 3x 3x 3x 3
786:2x 3x 131
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 3x 19 = 456
Therefore, the value for common factors is 456.
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 = 146726191584/(1x456)
LCM = 146726191584/456
LCM = 321767964
Thus, we can understand that the LCM of 361,972,786,532 is 321767964.
