HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 781, 132 i.e. 11 the largest integer that leaves a remainder zero for all numbers.
HCF of 781, 132 is 11 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 781, 132 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 781, 132 is 11.
HCF(781, 132) = 11
HCF of 781, 132 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 781, 132 is 11.
Highest Common Factor of 781,132 is 11
Step 1: Since 781 > 132, we apply the division lemma to 781 and 132, to get
781 = 132 x 5 + 121
Step 2: Since the reminder 132 ≠ 0, we apply division lemma to 121 and 132, to get
132 = 121 x 1 + 11
Step 3: We consider the new divisor 121 and the new remainder 11, and apply the division lemma to get
121 = 11 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 781 and 132 is 11
Notice that 11 = HCF(121,11) = HCF(132,121) = HCF(781,132) .
