HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 544, 856, 624 i.e. 8 the largest integer that leaves a remainder zero for all numbers.
HCF of 544, 856, 624 is 8 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 544, 856, 624 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 544, 856, 624 is 8.
HCF(544, 856, 624) = 8
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 544, 856, 624 is 8.
Step 1: Since 856 > 544, we apply the division lemma to 856 and 544, to get
856 = 544 x 1 + 312
Step 2: Since the reminder 544 ≠ 0, we apply division lemma to 312 and 544, to get
544 = 312 x 1 + 232
Step 3: We consider the new divisor 312 and the new remainder 232, and apply the division lemma to get
312 = 232 x 1 + 80
We consider the new divisor 232 and the new remainder 80,and apply the division lemma to get
232 = 80 x 2 + 72
We consider the new divisor 80 and the new remainder 72,and apply the division lemma to get
80 = 72 x 1 + 8
We consider the new divisor 72 and the new remainder 8,and apply the division lemma to get
72 = 8 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 544 and 856 is 8
Notice that 8 = HCF(72,8) = HCF(80,72) = HCF(232,80) = HCF(312,232) = HCF(544,312) = HCF(856,544) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 624 > 8, we apply the division lemma to 624 and 8, to get
624 = 8 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 8 and 624 is 8
Notice that 8 = HCF(624,8) .
Here are some samples of HCF using Euclid's Algorithm calculations.
1. What is the Euclid division algorithm?

2. what is the HCF of 544, 856, 624?
Answer: HCF of 544, 856, 624 is 8 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 544, 856, 624 using Euclid's Algorithm?
Answer: For arbitrary numbers 544, 856, 624 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
