HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 132, 336, 946 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 132, 336, 946 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 132, 336, 946 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 132, 336, 946 is 2.
HCF(132, 336, 946) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 132, 336, 946 is 2.
Step 1: Since 336 > 132, we apply the division lemma to 336 and 132, to get
336 = 132 x 2 + 72
Step 2: Since the reminder 132 ≠ 0, we apply division lemma to 72 and 132, to get
132 = 72 x 1 + 60
Step 3: We consider the new divisor 72 and the new remainder 60, and apply the division lemma to get
72 = 60 x 1 + 12
We consider the new divisor 60 and the new remainder 12, and apply the division lemma to get
60 = 12 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 132 and 336 is 12
Notice that 12 = HCF(60,12) = HCF(72,60) = HCF(132,72) = HCF(336,132) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 946 > 12, we apply the division lemma to 946 and 12, to get
946 = 12 x 78 + 10
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 10 and 12, to get
12 = 10 x 1 + 2
Step 3: We consider the new divisor 10 and the new remainder 2, and apply the division lemma to get
10 = 2 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 12 and 946 is 2
Notice that 2 = HCF(10,2) = HCF(12,10) = HCF(946,12) .
Here are some samples of HCF using Euclid's Algorithm calculations.
