HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 39, 13, 77, 792 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 39, 13, 77, 792 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, 13, 77, 792 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, 13, 77, 792 is 1.
HCF(39, 13, 77, 792) = 1
HCF of 39, 13, 77, 792 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, 13, 77, 792 is 1.
Highest Common Factor of 39,13,77,792 is 1
Step 1: Since 39 > 13, we apply the division lemma to 39 and 13, to get
39 = 13 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 13, the HCF of 39 and 13 is 13
Notice that 13 = HCF(39,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 77 > 13, we apply the division lemma to 77 and 13, to get
77 = 13 x 5 + 12
Step 2: Since the reminder 13 ≠ 0, we apply division lemma to 12 and 13, to get
13 = 12 x 1 + 1
Step 3: We consider the new divisor 12 and the new remainder 1, and apply the division lemma to get
12 = 1 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 13 and 77 is 1
Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(77,13) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 792 > 1, we apply the division lemma to 792 and 1, to get
792 = 1 x 792 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 792 is 1
Notice that 1 = HCF(792,1) .
