HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 788, 615, 517, 327 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 788, 615, 517, 327 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 788, 615, 517, 327 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 788, 615, 517, 327 is 1.
HCF(788, 615, 517, 327) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 788, 615, 517, 327 is 1.
Step 1: Since 788 > 615, we apply the division lemma to 788 and 615, to get
788 = 615 x 1 + 173
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 173 and 615, to get
615 = 173 x 3 + 96
Step 3: We consider the new divisor 173 and the new remainder 96, and apply the division lemma to get
173 = 96 x 1 + 77
We consider the new divisor 96 and the new remainder 77,and apply the division lemma to get
96 = 77 x 1 + 19
We consider the new divisor 77 and the new remainder 19,and apply the division lemma to get
77 = 19 x 4 + 1
We consider the new divisor 19 and the new remainder 1,and apply the division lemma to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 788 and 615 is 1
Notice that 1 = HCF(19,1) = HCF(77,19) = HCF(96,77) = HCF(173,96) = HCF(615,173) = HCF(788,615) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 517 > 1, we apply the division lemma to 517 and 1, to get
517 = 1 x 517 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 517 is 1
Notice that 1 = HCF(517,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 327 > 1, we apply the division lemma to 327 and 1, to get
327 = 1 x 327 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 327 is 1
Notice that 1 = HCF(327,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 788, 615, 517, 327?
Answer: HCF of 788, 615, 517, 327 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 788, 615, 517, 327 using Euclid's Algorithm?
Answer: For arbitrary numbers 788, 615, 517, 327 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
