HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 77, 385 i.e. 77 the largest integer that leaves a remainder zero for all numbers.
HCF of 77, 385 is 77 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 77, 385 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 77, 385 is 77.
HCF(77, 385) = 77
HCF of 77, 385 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 77, 385 is 77.
Highest Common Factor of 77,385 is 77
Step 1: Since 385 > 77, we apply the division lemma to 385 and 77, to get
385 = 77 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 77, the HCF of 77 and 385 is 77
Notice that 77 = HCF(385,77) .
