HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 792, 198 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 792, 198 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 497, 792, 198 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 497, 792, 198 is 1.
HCF(497, 792, 198) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 792, 198 is 1.
Step 1: Since 792 > 497, we apply the division lemma to 792 and 497, to get
792 = 497 x 1 + 295
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 295 and 497, to get
497 = 295 x 1 + 202
Step 3: We consider the new divisor 295 and the new remainder 202, and apply the division lemma to get
295 = 202 x 1 + 93
We consider the new divisor 202 and the new remainder 93,and apply the division lemma to get
202 = 93 x 2 + 16
We consider the new divisor 93 and the new remainder 16,and apply the division lemma to get
93 = 16 x 5 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 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 497 and 792 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(93,16) = HCF(202,93) = HCF(295,202) = HCF(497,295) = HCF(792,497) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 198 > 1, we apply the division lemma to 198 and 1, to get
198 = 1 x 198 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 198 is 1
Notice that 1 = HCF(198,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
