Given numbers are 218,147,763,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 218,147,763,691 is 22143786.
Find LCM of 218,147,763,691 with Prime Factorization
7 | 218, 147, 763, 691 |
109 | 218, 21, 109, 691 |
2, 21, 1, 691 |
Multiply the prime numbers at the bottom and the left side.
7 x 109 x 2 x 21 x 1 x 691 = 22143786
Therefore, the lowest common multiple of 218,147,763,691 is 22143786.
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.
218 x 147 x 763 x 691 = 16895708718
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.
218 : 1, 2, 109, 218
147 : 1, 3, 7, 21, 49, 147
763 : 1, 7, 109, 763
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 218,147,763,691, is 1.
Now, the common factors can be found like this.
218:2x 109
147:3x 7x 7
763:7x 109
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 109 = 763
Therefore, the value for common factors is 763.
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 = 16895708718/(1x763)
LCM = 16895708718/763
LCM = 22143786
Thus, we can understand that the LCM of 218,147,763,691 is 22143786.
