HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 622, 968, 520 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 622, 968, 520 is 2 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 622, 968, 520 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 622, 968, 520 is 2.
HCF(622, 968, 520) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 622, 968, 520 is 2.
Step 1: Since 968 > 622, we apply the division lemma to 968 and 622, to get
968 = 622 x 1 + 346
Step 2: Since the reminder 622 ≠ 0, we apply division lemma to 346 and 622, to get
622 = 346 x 1 + 276
Step 3: We consider the new divisor 346 and the new remainder 276, and apply the division lemma to get
346 = 276 x 1 + 70
We consider the new divisor 276 and the new remainder 70,and apply the division lemma to get
276 = 70 x 3 + 66
We consider the new divisor 70 and the new remainder 66,and apply the division lemma to get
70 = 66 x 1 + 4
We consider the new divisor 66 and the new remainder 4,and apply the division lemma to get
66 = 4 x 16 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 622 and 968 is 2
Notice that 2 = HCF(4,2) = HCF(66,4) = HCF(70,66) = HCF(276,70) = HCF(346,276) = HCF(622,346) = HCF(968,622) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 520 > 2, we apply the division lemma to 520 and 2, to get
520 = 2 x 260 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 520 is 2
Notice that 2 = HCF(520,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 622, 968, 520?
Answer: HCF of 622, 968, 520 is 2 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 622, 968, 520 using Euclid's Algorithm?
Answer: For arbitrary numbers 622, 968, 520 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
