Given numbers are 948,978,626,240,657
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 948,978,626,240,657 is 211843132560.
Find LCM of 948,978,626,240,657 with Prime Factorization
| 2 | 948, 978, 626, 240, 657 |
| 2 | 474, 489, 313, 120, 657 |
| 3 | 237, 489, 313, 60, 657 |
| 79, 163, 313, 20, 219 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 79 x 163 x 313 x 20 x 219 = 211843132560
Therefore, the lowest common multiple of 948,978,626,240,657 is 211843132560.
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.
948 x 978 x 626 x 240 x 657 = 91516233265920
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.
948 : 1, 2, 3, 4, 6, 12, 79, 158, 237, 316, 474, 948
978 : 1, 2, 3, 6, 163, 326, 489, 978
626 : 1, 2, 313, 626
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
657 : 1, 3, 9, 73, 219, 657
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 948,978,626,240,657, is 1.
Now, the common factors can be found like this.
948:2x 2x 3x 79
978:2x 3x 163
626:2x 313
240:2x 2x 2x 2x 3x 5
657:3x 3x 73
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 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 91516233265920/(1x432)
LCM = 91516233265920/432
LCM = 211843132560
Thus, we can understand that the LCM of 948,978,626,240,657 is 211843132560.
