HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 39, 78, 962, 231 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 39, 78, 962, 231 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 39, 78, 962, 231 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 39, 78, 962, 231 is 1.
HCF(39, 78, 962, 231) = 1
HCF of 39, 78, 962, 231 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 39, 78, 962, 231 is 1.
Highest Common Factor of 39,78,962,231 is 1
Step 1: Since 78 > 39, we apply the division lemma to 78 and 39, to get
78 = 39 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 39 and 78 is 39
Notice that 39 = HCF(78,39) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 962 > 39, we apply the division lemma to 962 and 39, to get
962 = 39 x 24 + 26
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 26 and 39, to get
39 = 26 x 1 + 13
Step 3: We consider the new divisor 26 and the new remainder 13, and apply the division lemma to get
26 = 13 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 39 and 962 is 13
Notice that 13 = HCF(26,13) = HCF(39,26) = HCF(962,39) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 231 > 13, we apply the division lemma to 231 and 13, to get
231 = 13 x 17 + 10
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 10 and 13, to get
13 = 10 x 1 + 3
Step 3: We consider the new divisor 10 and the new remainder 3, and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 231 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(231,13) .
