HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 66, 162, 332, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 66, 162, 332, 225 is 1 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, 162, 332, 225 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, 162, 332, 225 is 1.
HCF(66, 162, 332, 225) = 1
HCF of 66, 162, 332, 225 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, 162, 332, 225 is 1.
Highest Common Factor of 66,162,332,225 is 1
Step 1: Since 162 > 66, we apply the division lemma to 162 and 66, to get
162 = 66 x 2 + 30
Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 30 and 66, to get
66 = 30 x 2 + 6
Step 3: We consider the new divisor 30 and the new remainder 6, and apply the division lemma to get
30 = 6 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 66 and 162 is 6
Notice that 6 = HCF(30,6) = HCF(66,30) = HCF(162,66) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 332 > 6, we apply the division lemma to 332 and 6, to get
332 = 6 x 55 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 332 is 2
Notice that 2 = HCF(6,2) = HCF(332,6) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 225 > 2, we apply the division lemma to 225 and 2, to get
225 = 2 x 112 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 225 is 1
Notice that 1 = HCF(2,1) = HCF(225,2) .
