HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 175, 45 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 175, 45 is 5 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 175, 45 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 175, 45 is 5.
HCF(175, 45) = 5
HCF of 175, 45 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 175, 45 is 5.
Highest Common Factor of 175,45 is 5
Step 1: Since 175 > 45, we apply the division lemma to 175 and 45, to get
175 = 45 x 3 + 40
Step 2: Since the reminder 45 ≠ 0, we apply division lemma to 40 and 45, to get
45 = 40 x 1 + 5
Step 3: We consider the new divisor 40 and the new remainder 5, and apply the division lemma to get
40 = 5 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 175 and 45 is 5
Notice that 5 = HCF(40,5) = HCF(45,40) = HCF(175,45) .
