Given numbers are 784,971,118,198
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,971,118,198 is 4446543024.
Find LCM of 784,971,118,198 with Prime Factorization
2 | 784, 971, 118, 198 |
392, 971, 59, 99 |
Multiply the prime numbers at the bottom and the left side.
2 x 392 x 971 x 59 x 99 = 4446543024
Therefore, the lowest common multiple of 784,971,118,198 is 4446543024.
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.
784 x 971 x 118 x 198 = 17786172096
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
971 : 1, 971
118 : 1, 2, 59, 118
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,971,118,198, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
971:971
118:2x 59
198:2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 17786172096/(1x4)
LCM = 17786172096/4
LCM = 4446543024
Thus, we can understand that the LCM of 784,971,118,198 is 4446543024.
