HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9775, 640 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 9775, 640 is 5 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 9775, 640 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 9775, 640 is 5.
HCF(9775, 640) = 5
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9775, 640 is 5.
Step 1: Since 9775 > 640, we apply the division lemma to 9775 and 640, to get
9775 = 640 x 15 + 175
Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 175 and 640, to get
640 = 175 x 3 + 115
Step 3: We consider the new divisor 175 and the new remainder 115, and apply the division lemma to get
175 = 115 x 1 + 60
We consider the new divisor 115 and the new remainder 60,and apply the division lemma to get
115 = 60 x 1 + 55
We consider the new divisor 60 and the new remainder 55,and apply the division lemma to get
60 = 55 x 1 + 5
We consider the new divisor 55 and the new remainder 5,and apply the division lemma to get
55 = 5 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 9775 and 640 is 5
Notice that 5 = HCF(55,5) = HCF(60,55) = HCF(115,60) = HCF(175,115) = HCF(640,175) = HCF(9775,640) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 9775, 640?
Answer: HCF of 9775, 640 is 5 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 9775, 640 using Euclid's Algorithm?
Answer: For arbitrary numbers 9775, 640 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
