HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 16, 234, 989 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 16, 234, 989 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 16, 234, 989 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 16, 234, 989 is 1.
HCF(16, 234, 989) = 1
HCF of 16, 234, 989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 16, 234, 989 is 1.
Highest Common Factor of 16,234,989 is 1
Step 1: Since 234 > 16, we apply the division lemma to 234 and 16, to get
234 = 16 x 14 + 10
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 10 and 16, to get
16 = 10 x 1 + 6
Step 3: We consider the new divisor 10 and the new remainder 6, and apply the division lemma to get
10 = 6 x 1 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 16 and 234 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(16,10) = HCF(234,16) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 989 > 2, we apply the division lemma to 989 and 2, to get
989 = 2 x 494 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 989 is 1
Notice that 1 = HCF(2,1) = HCF(989,2) .
