Given numbers are 398,763,199,980,983
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,763,199,980,983 is 20895807940.
Find LCM of 398,763,199,980,983 with Prime Factorization
2 | 398, 763, 199, 980, 983 |
7 | 199, 763, 199, 490, 983 |
199 | 199, 109, 199, 70, 983 |
1, 109, 1, 70, 983 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 199 x 1 x 109 x 1 x 70 x 983 = 20895807940
Therefore, the lowest common multiple of 398,763,199,980,983 is 20895807940.
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.
398 x 763 x 199 x 980 x 983 = 58215720920840
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.
398 : 1, 2, 199, 398
763 : 1, 7, 109, 763
199 : 1, 199
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
983 : 1, 983
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,763,199,980,983, is 1.
Now, the common factors can be found like this.
398:2x 199
763:7x 109
199:199
980:2x 2x 5x 7x 7
983:983
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 199 = 2786
Therefore, the value for common factors is 2786.
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 = 58215720920840/(1x2786)
LCM = 58215720920840/2786
LCM = 20895807940
Thus, we can understand that the LCM of 398,763,199,980,983 is 20895807940.
