HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 77130 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 497, 77130 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 497, 77130 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 497, 77130 is 1.
HCF(497, 77130) = 1
HCF of 497, 77130 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 497, 77130 is 1.
Highest Common Factor of 497,77130 is 1
Step 1: Since 77130 > 497, we apply the division lemma to 77130 and 497, to get
77130 = 497 x 155 + 95
Step 2: Since the reminder 497 ≠ 0, we apply division lemma to 95 and 497, to get
497 = 95 x 5 + 22
Step 3: We consider the new divisor 95 and the new remainder 22, and apply the division lemma to get
95 = 22 x 4 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 497 and 77130 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(95,22) = HCF(497,95) = HCF(77130,497) .
