HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 40, 77, 89, 896 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 40, 77, 89, 896 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 40, 77, 89, 896 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 40, 77, 89, 896 is 1.
HCF(40, 77, 89, 896) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 40, 77, 89, 896 is 1.
Step 1: Since 77 > 40, we apply the division lemma to 77 and 40, to get
77 = 40 x 1 + 37
Step 2: Since the reminder 40 ≠ 0, we apply division lemma to 37 and 40, to get
40 = 37 x 1 + 3
Step 3: We consider the new divisor 37 and the new remainder 3, and apply the division lemma to get
37 = 3 x 12 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma 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 40 and 77 is 1
Notice that 1 = HCF(3,1) = HCF(37,3) = HCF(40,37) = HCF(77,40) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 89 > 1, we apply the division lemma to 89 and 1, to get
89 = 1 x 89 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 89 is 1
Notice that 1 = HCF(89,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 896 > 1, we apply the division lemma to 896 and 1, to get
896 = 1 x 896 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 896 is 1
Notice that 1 = HCF(896,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 40, 77, 89, 896?
Answer: HCF of 40, 77, 89, 896 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 40, 77, 89, 896 using Euclid's Algorithm?
Answer: For arbitrary numbers 40, 77, 89, 896 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
