HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 64, 68, 13, 791 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 64, 68, 13, 791 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 64, 68, 13, 791 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 64, 68, 13, 791 is 1.
HCF(64, 68, 13, 791) = 1
HCF of 64, 68, 13, 791 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 64, 68, 13, 791 is 1.
Highest Common Factor of 64,68,13,791 is 1
Step 1: Since 68 > 64, we apply the division lemma to 68 and 64, to get
68 = 64 x 1 + 4
Step 2: Since the reminder 64 ≠ 0, we apply division lemma to 4 and 64, to get
64 = 4 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 64 and 68 is 4
Notice that 4 = HCF(64,4) = HCF(68,64) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 13 > 4, we apply the division lemma to 13 and 4, to get
13 = 4 x 3 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 13 is 1
Notice that 1 = HCF(4,1) = HCF(13,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 791 > 1, we apply the division lemma to 791 and 1, to get
791 = 1 x 791 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 791 is 1
Notice that 1 = HCF(791,1) .
