HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 923, 199, 663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 923, 199, 663 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 923, 199, 663 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 923, 199, 663 is 1.
HCF(923, 199, 663) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 923, 199, 663 is 1.
Step 1: Since 923 > 199, we apply the division lemma to 923 and 199, to get
923 = 199 x 4 + 127
Step 2: Since the reminder 199 ≠ 0, we apply division lemma to 127 and 199, to get
199 = 127 x 1 + 72
Step 3: We consider the new divisor 127 and the new remainder 72, and apply the division lemma to get
127 = 72 x 1 + 55
We consider the new divisor 72 and the new remainder 55,and apply the division lemma to get
72 = 55 x 1 + 17
We consider the new divisor 55 and the new remainder 17,and apply the division lemma to get
55 = 17 x 3 + 4
We consider the new divisor 17 and the new remainder 4,and apply the division lemma to get
17 = 4 x 4 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 923 and 199 is 1
Notice that 1 = HCF(4,1) = HCF(17,4) = HCF(55,17) = HCF(72,55) = HCF(127,72) = HCF(199,127) = HCF(923,199) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 663 > 1, we apply the division lemma to 663 and 1, to get
663 = 1 x 663 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 663 is 1
Notice that 1 = HCF(663,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
