Given numbers are 620,546,818,397,812
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 620,546,818,397,812 is 797014365420.
Find LCM of 620,546,818,397,812 with Prime Factorization
| 2 | 620, 546, 818, 397, 812 |
| 2 | 310, 273, 409, 397, 406 |
| 7 | 155, 273, 409, 397, 203 |
| 155, 39, 409, 397, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 155 x 39 x 409 x 397 x 29 = 797014365420
Therefore, the lowest common multiple of 620,546,818,397,812 is 797014365420.
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.
620 x 546 x 818 x 397 x 812 = 89265608927040
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
818 : 1, 2, 409, 818
397 : 1, 397
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,546,818,397,812, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
546:2x 3x 7x 13
818:2x 409
397:397
812:2x 2x 7x 29
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 = 89265608927040/(1x112)
LCM = 89265608927040/112
LCM = 797014365420
Thus, we can understand that the LCM of 620,546,818,397,812 is 797014365420.
