HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 635, 60, 475 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 635, 60, 475 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 635, 60, 475 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 635, 60, 475 is 5.
HCF(635, 60, 475) = 5
HCF of 635, 60, 475 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 635, 60, 475 is 5.
Highest Common Factor of 635,60,475 is 5
Step 1: Since 635 > 60, we apply the division lemma to 635 and 60, to get
635 = 60 x 10 + 35
Step 2: Since the reminder 60 ≠ 0, we apply division lemma to 35 and 60, to get
60 = 35 x 1 + 25
Step 3: We consider the new divisor 35 and the new remainder 25, and apply the division lemma to get
35 = 25 x 1 + 10
We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get
25 = 10 x 2 + 5
We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get
10 = 5 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 635 and 60 is 5
Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(35,25) = HCF(60,35) = HCF(635,60) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 475 > 5, we apply the division lemma to 475 and 5, to get
475 = 5 x 95 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 475 is 5
Notice that 5 = HCF(475,5) .
