HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 673, 198 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 673, 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 673, 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 673, 198 is 1.
HCF(673, 198) = 1
HCF of 673, 198 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 673, 198 is 1.
Highest Common Factor of 673,198 is 1
Step 1: Since 673 > 198, we apply the division lemma to 673 and 198, to get
673 = 198 x 3 + 79
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 79 and 198, to get
198 = 79 x 2 + 40
Step 3: We consider the new divisor 79 and the new remainder 40, and apply the division lemma to get
79 = 40 x 1 + 39
We consider the new divisor 40 and the new remainder 39,and apply the division lemma to get
40 = 39 x 1 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 673 and 198 is 1
Notice that 1 = HCF(39,1) = HCF(40,39) = HCF(79,40) = HCF(198,79) = HCF(673,198) .
