HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 84820 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 84820 is 10 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, 84820 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, 84820 is 10.
HCF(770, 84820) = 10
HCF of 770, 84820 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, 84820 is 10.
Highest Common Factor of 770,84820 is 10
Step 1: Since 84820 > 770, we apply the division lemma to 84820 and 770, to get
84820 = 770 x 110 + 120
Step 2: Since the reminder 770 ≠ 0, we apply division lemma to 120 and 770, to get
770 = 120 x 6 + 50
Step 3: We consider the new divisor 120 and the new remainder 50, and apply the division lemma to get
120 = 50 x 2 + 20
We consider the new divisor 50 and the new remainder 20,and apply the division lemma to get
50 = 20 x 2 + 10
We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get
20 = 10 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 770 and 84820 is 10
Notice that 10 = HCF(20,10) = HCF(50,20) = HCF(120,50) = HCF(770,120) = HCF(84820,770) .
