HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 646, 132 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 970, 646, 132 is 2 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 970, 646, 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 970, 646, 132 is 2.
HCF(970, 646, 132) = 2
HCF of 970, 646, 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 970, 646, 132 is 2.
Highest Common Factor of 970,646,132 is 2
Step 1: Since 970 > 646, we apply the division lemma to 970 and 646, to get
970 = 646 x 1 + 324
Step 2: Since the reminder 646 ≠ 0, we apply division lemma to 324 and 646, to get
646 = 324 x 1 + 322
Step 3: We consider the new divisor 324 and the new remainder 322, and apply the division lemma to get
324 = 322 x 1 + 2
We consider the new divisor 322 and the new remainder 2, and apply the division lemma to get
322 = 2 x 161 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 970 and 646 is 2
Notice that 2 = HCF(322,2) = HCF(324,322) = HCF(646,324) = HCF(970,646) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 132 > 2, we apply the division lemma to 132 and 2, to get
132 = 2 x 66 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 132 is 2
Notice that 2 = HCF(132,2) .
