HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 395, 77010 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 395, 77010 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 395, 77010 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 395, 77010 is 5.
HCF(395, 77010) = 5
HCF of 395, 77010 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 395, 77010 is 5.
Highest Common Factor of 395,77010 is 5
Step 1: Since 77010 > 395, we apply the division lemma to 77010 and 395, to get
77010 = 395 x 194 + 380
Step 2: Since the reminder 395 ≠ 0, we apply division lemma to 380 and 395, to get
395 = 380 x 1 + 15
Step 3: We consider the new divisor 380 and the new remainder 15, and apply the division lemma to get
380 = 15 x 25 + 5
We consider the new divisor 15 and the new remainder 5, and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 395 and 77010 is 5
Notice that 5 = HCF(15,5) = HCF(380,15) = HCF(395,380) = HCF(77010,395) .
