HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 634, 471, 75 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 634, 471, 75 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 634, 471, 75 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 634, 471, 75 is 1.
HCF(634, 471, 75) = 1
HCF of 634, 471, 75 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 634, 471, 75 is 1.
Highest Common Factor of 634,471,75 is 1
Step 1: Since 634 > 471, we apply the division lemma to 634 and 471, to get
634 = 471 x 1 + 163
Step 2: Since the reminder 471 ≠ 0, we apply division lemma to 163 and 471, to get
471 = 163 x 2 + 145
Step 3: We consider the new divisor 163 and the new remainder 145, and apply the division lemma to get
163 = 145 x 1 + 18
We consider the new divisor 145 and the new remainder 18,and apply the division lemma to get
145 = 18 x 8 + 1
We consider the new divisor 18 and the new remainder 1,and apply the division lemma to get
18 = 1 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 634 and 471 is 1
Notice that 1 = HCF(18,1) = HCF(145,18) = HCF(163,145) = HCF(471,163) = HCF(634,471) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 75 > 1, we apply the division lemma to 75 and 1, to get
75 = 1 x 75 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 75 is 1
Notice that 1 = HCF(75,1) .
