HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 921, 750, 88 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 921, 750, 88 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 921, 750, 88 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 921, 750, 88 is 1.
HCF(921, 750, 88) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 921, 750, 88 is 1.
Step 1: Since 921 > 750, we apply the division lemma to 921 and 750, to get
921 = 750 x 1 + 171
Step 2: Since the reminder 750 ≠ 0, we apply division lemma to 171 and 750, to get
750 = 171 x 4 + 66
Step 3: We consider the new divisor 171 and the new remainder 66, and apply the division lemma to get
171 = 66 x 2 + 39
We consider the new divisor 66 and the new remainder 39,and apply the division lemma to get
66 = 39 x 1 + 27
We consider the new divisor 39 and the new remainder 27,and apply the division lemma to get
39 = 27 x 1 + 12
We consider the new divisor 27 and the new remainder 12,and apply the division lemma to get
27 = 12 x 2 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 921 and 750 is 3
Notice that 3 = HCF(12,3) = HCF(27,12) = HCF(39,27) = HCF(66,39) = HCF(171,66) = HCF(750,171) = HCF(921,750) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 88 > 3, we apply the division lemma to 88 and 3, to get
88 = 3 x 29 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 88 is 1
Notice that 1 = HCF(3,1) = HCF(88,3) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 921, 750, 88?
Answer: HCF of 921, 750, 88 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 921, 750, 88 using Euclid's Algorithm?
Answer: For arbitrary numbers 921, 750, 88 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
