HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 860, 620 i.e. 10 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 860, 620 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, 860, 620 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, 860, 620 is 10.
HCF(770, 860, 620) = 10
HCF of 770, 860, 620 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, 860, 620 is 10.
Highest Common Factor of 770,860,620 is 10
Step 1: Since 860 > 770, we apply the division lemma to 860 and 770, to get
860 = 770 x 1 + 90
Step 2: Since the reminder 770 ≠ 0, we apply division lemma to 90 and 770, to get
770 = 90 x 8 + 50
Step 3: We consider the new divisor 90 and the new remainder 50, and apply the division lemma to get
90 = 50 x 1 + 40
We consider the new divisor 50 and the new remainder 40,and apply the division lemma to get
50 = 40 x 1 + 10
We consider the new divisor 40 and the new remainder 10,and apply the division lemma to get
40 = 10 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 770 and 860 is 10
Notice that 10 = HCF(40,10) = HCF(50,40) = HCF(90,50) = HCF(770,90) = HCF(860,770) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 620 > 10, we apply the division lemma to 620 and 10, to get
620 = 10 x 62 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 10 and 620 is 10
Notice that 10 = HCF(620,10) .
