HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 291, 756 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 291, 756 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 291, 756 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 291, 756 is 3.
HCF(291, 756) = 3
HCF of 291, 756 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 291, 756 is 3.
Highest Common Factor of 291,756 is 3
Step 1: Since 756 > 291, we apply the division lemma to 756 and 291, to get
756 = 291 x 2 + 174
Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 174 and 291, to get
291 = 174 x 1 + 117
Step 3: We consider the new divisor 174 and the new remainder 117, and apply the division lemma to get
174 = 117 x 1 + 57
We consider the new divisor 117 and the new remainder 57,and apply the division lemma to get
117 = 57 x 2 + 3
We consider the new divisor 57 and the new remainder 3,and apply the division lemma to get
57 = 3 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 291 and 756 is 3
Notice that 3 = HCF(57,3) = HCF(117,57) = HCF(174,117) = HCF(291,174) = HCF(756,291) .
