HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 66, 132, 100 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 66, 132, 100 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 66, 132, 100 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 66, 132, 100 is 2.
HCF(66, 132, 100) = 2
HCF of 66, 132, 100 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 66, 132, 100 is 2.
Highest Common Factor of 66,132,100 is 2
Step 1: Since 132 > 66, we apply the division lemma to 132 and 66, to get
132 = 66 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 66, the HCF of 66 and 132 is 66
Notice that 66 = HCF(132,66) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 100 > 66, we apply the division lemma to 100 and 66, to get
100 = 66 x 1 + 34
Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 34 and 66, to get
66 = 34 x 1 + 32
Step 3: We consider the new divisor 34 and the new remainder 32, and apply the division lemma to get
34 = 32 x 1 + 2
We consider the new divisor 32 and the new remainder 2, and apply the division lemma to get
32 = 2 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 66 and 100 is 2
Notice that 2 = HCF(32,2) = HCF(34,32) = HCF(66,34) = HCF(100,66) .
