HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 395 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 395 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 785, 395 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 785, 395 is 5.
HCF(785, 395) = 5
HCF of 785, 395 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 395 is 5.
Highest Common Factor of 785,395 is 5
Step 1: Since 785 > 395, we apply the division lemma to 785 and 395, to get
785 = 395 x 1 + 390
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 390 and 395, to get
395 = 390 x 1 + 5
Step 3: We consider the new divisor 390 and the new remainder 5, and apply the division lemma to get
390 = 5 x 78 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 785 and 395 is 5
Notice that 5 = HCF(390,5) = HCF(395,390) = HCF(785,395) .
