HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 771, 303 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 771, 303 is 3 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 771, 303 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 771, 303 is 3.
HCF(771, 303) = 3
HCF of 771, 303 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 771, 303 is 3.
Highest Common Factor of 771,303 is 3
Step 1: Since 771 > 303, we apply the division lemma to 771 and 303, to get
771 = 303 x 2 + 165
Step 2: Since the reminder 303 ≠ 0, we apply division lemma to 165 and 303, to get
303 = 165 x 1 + 138
Step 3: We consider the new divisor 165 and the new remainder 138, and apply the division lemma to get
165 = 138 x 1 + 27
We consider the new divisor 138 and the new remainder 27,and apply the division lemma to get
138 = 27 x 5 + 3
We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 771 and 303 is 3
Notice that 3 = HCF(27,3) = HCF(138,27) = HCF(165,138) = HCF(303,165) = HCF(771,303) .
