HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 635, 845 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 635, 845 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, 845 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, 845 is 5.
HCF(635, 845) = 5
HCF of 635, 845 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, 845 is 5.
Highest Common Factor of 635,845 is 5
Step 1: Since 845 > 635, we apply the division lemma to 845 and 635, to get
845 = 635 x 1 + 210
Step 2: Since the reminder 635 ≠ 0, we apply division lemma to 210 and 635, to get
635 = 210 x 3 + 5
Step 3: We consider the new divisor 210 and the new remainder 5, and apply the division lemma to get
210 = 5 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 635 and 845 is 5
Notice that 5 = HCF(210,5) = HCF(635,210) = HCF(845,635) .
