HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 728 i.e. 14 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 728 is 14 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 770, 728 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 770, 728 is 14.
HCF(770, 728) = 14
HCF of 770, 728 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 728 is 14.
Highest Common Factor of 770,728 is 14
Step 1: Since 770 > 728, we apply the division lemma to 770 and 728, to get
770 = 728 x 1 + 42
Step 2: Since the reminder 728 ≠ 0, we apply division lemma to 42 and 728, to get
728 = 42 x 17 + 14
Step 3: We consider the new divisor 42 and the new remainder 14, and apply the division lemma to get
42 = 14 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 770 and 728 is 14
Notice that 14 = HCF(42,14) = HCF(728,42) = HCF(770,728) .
