HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 972, 132 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 972, 132 is 12 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 972, 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 972, 132 is 12.
HCF(972, 132) = 12
HCF of 972, 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 972, 132 is 12.
Highest Common Factor of 972,132 is 12
Step 1: Since 972 > 132, we apply the division lemma to 972 and 132, to get
972 = 132 x 7 + 48
Step 2: Since the reminder 132 ≠ 0, we apply division lemma to 48 and 132, to get
132 = 48 x 2 + 36
Step 3: We consider the new divisor 48 and the new remainder 36, and apply the division lemma to get
48 = 36 x 1 + 12
We consider the new divisor 36 and the new remainder 12, and apply the division lemma to get
36 = 12 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 972 and 132 is 12
Notice that 12 = HCF(36,12) = HCF(48,36) = HCF(132,48) = HCF(972,132) .
