Given numbers are 648,611,766,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 648,611,766,188 is 151640424.
Find LCM of 648,611,766,188 with Prime Factorization
| 2 | 648, 611, 766, 188 |
| 2 | 324, 611, 383, 94 |
| 47 | 162, 611, 383, 47 |
| 162, 13, 383, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 47 x 162 x 13 x 383 x 1 = 151640424
Therefore, the lowest common multiple of 648,611,766,188 is 151640424.
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.
648 x 611 x 766 x 188 = 57016799424
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
611 : 1, 13, 47, 611
766 : 1, 2, 383, 766
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,611,766,188, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
611:13x 47
766:2x 383
188:2x 2x 47
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 47 = 376
Therefore, the value for common factors is 376.
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 = 57016799424/(1x376)
LCM = 57016799424/376
LCM = 151640424
Thus, we can understand that the LCM of 648,611,766,188 is 151640424.
