HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 77, 425 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 77, 425 is 1 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, 425 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, 425 is 1.
HCF(77, 425) = 1
HCF of 77, 425 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, 425 is 1.
Highest Common Factor of 77,425 is 1
Step 1: Since 425 > 77, we apply the division lemma to 425 and 77, to get
425 = 77 x 5 + 40
Step 2: Since the reminder 77 ≠ 0, we apply division lemma to 40 and 77, to get
77 = 40 x 1 + 37
Step 3: We consider the new divisor 40 and the new remainder 37, and apply the division lemma to get
40 = 37 x 1 + 3
We consider the new divisor 37 and the new remainder 3,and apply the division lemma to get
37 = 3 x 12 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 77 and 425 is 1
Notice that 1 = HCF(3,1) = HCF(37,3) = HCF(40,37) = HCF(77,40) = HCF(425,77) .
