HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 773, 209 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 773, 209 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 773, 209 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 773, 209 is 1.
HCF(773, 209) = 1
HCF of 773, 209 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 773, 209 is 1.
Highest Common Factor of 773,209 is 1
Step 1: Since 773 > 209, we apply the division lemma to 773 and 209, to get
773 = 209 x 3 + 146
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 146 and 209, to get
209 = 146 x 1 + 63
Step 3: We consider the new divisor 146 and the new remainder 63, and apply the division lemma to get
146 = 63 x 2 + 20
We consider the new divisor 63 and the new remainder 20,and apply the division lemma to get
63 = 20 x 3 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma 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 773 and 209 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(63,20) = HCF(146,63) = HCF(209,146) = HCF(773,209) .
