HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 173, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 173, 425 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 173, 425 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 173, 425 is 1.
HCF(173, 425) = 1
HCF of 173, 425 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 173, 425 is 1.
Highest Common Factor of 173,425 is 1
Step 1: Since 425 > 173, we apply the division lemma to 425 and 173, to get
425 = 173 x 2 + 79
Step 2: Since the reminder 173 ≠ 0, we apply division lemma to 79 and 173, to get
173 = 79 x 2 + 15
Step 3: We consider the new divisor 79 and the new remainder 15, and apply the division lemma to get
79 = 15 x 5 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 173 and 425 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(79,15) = HCF(173,79) = HCF(425,173) .
