HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 916, 602, 775 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 916, 602, 775 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 916, 602, 775 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 916, 602, 775 is 1.
HCF(916, 602, 775) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 916, 602, 775 is 1.
Step 1: Since 916 > 602, we apply the division lemma to 916 and 602, to get
916 = 602 x 1 + 314
Step 2: Since the reminder 602 ≠ 0, we apply division lemma to 314 and 602, to get
602 = 314 x 1 + 288
Step 3: We consider the new divisor 314 and the new remainder 288, and apply the division lemma to get
314 = 288 x 1 + 26
We consider the new divisor 288 and the new remainder 26,and apply the division lemma to get
288 = 26 x 11 + 2
We consider the new divisor 26 and the new remainder 2,and apply the division lemma to get
26 = 2 x 13 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 916 and 602 is 2
Notice that 2 = HCF(26,2) = HCF(288,26) = HCF(314,288) = HCF(602,314) = HCF(916,602) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 775 > 2, we apply the division lemma to 775 and 2, to get
775 = 2 x 387 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 2 and 775 is 1
Notice that 1 = HCF(2,1) = HCF(775,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 916, 602, 775?
Answer: HCF of 916, 602, 775 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 916, 602, 775 using Euclid's Algorithm?
Answer: For arbitrary numbers 916, 602, 775 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
