HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 85, 775, 635 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 85, 775, 635 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 85, 775, 635 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 85, 775, 635 is 5.
HCF(85, 775, 635) = 5
HCF of 85, 775, 635 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 85, 775, 635 is 5.
Highest Common Factor of 85,775,635 is 5
Step 1: Since 775 > 85, we apply the division lemma to 775 and 85, to get
775 = 85 x 9 + 10
Step 2: Since the reminder 85 ≠ 0, we apply division lemma to 10 and 85, to get
85 = 10 x 8 + 5
Step 3: 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 85 and 775 is 5
Notice that 5 = HCF(10,5) = HCF(85,10) = HCF(775,85) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 635 > 5, we apply the division lemma to 635 and 5, to get
635 = 5 x 127 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 635 is 5
Notice that 5 = HCF(635,5) .
