HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 838, 624, 822 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 838, 624, 822 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 838, 624, 822 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 838, 624, 822 is 2.
HCF(838, 624, 822) = 2
HCF of 838, 624, 822 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 838, 624, 822 is 2.
Highest Common Factor of 838,624,822 is 2
Step 1: Since 838 > 624, we apply the division lemma to 838 and 624, to get
838 = 624 x 1 + 214
Step 2: Since the reminder 624 ≠ 0, we apply division lemma to 214 and 624, to get
624 = 214 x 2 + 196
Step 3: We consider the new divisor 214 and the new remainder 196, and apply the division lemma to get
214 = 196 x 1 + 18
We consider the new divisor 196 and the new remainder 18,and apply the division lemma to get
196 = 18 x 10 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 838 and 624 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(196,18) = HCF(214,196) = HCF(624,214) = HCF(838,624) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 822 > 2, we apply the division lemma to 822 and 2, to get
822 = 2 x 411 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 822 is 2
Notice that 2 = HCF(822,2) .
