HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 810, 7640, 6121 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 810, 7640, 6121 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 810, 7640, 6121 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 810, 7640, 6121 is 1.
HCF(810, 7640, 6121) = 1
HCF of 810, 7640, 6121 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 810, 7640, 6121 is 1.
Highest Common Factor of 810,7640,6121 is 1
Step 1: Since 7640 > 810, we apply the division lemma to 7640 and 810, to get
7640 = 810 x 9 + 350
Step 2: Since the reminder 810 ≠ 0, we apply division lemma to 350 and 810, to get
810 = 350 x 2 + 110
Step 3: We consider the new divisor 350 and the new remainder 110, and apply the division lemma to get
350 = 110 x 3 + 20
We consider the new divisor 110 and the new remainder 20,and apply the division lemma to get
110 = 20 x 5 + 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 810 and 7640 is 10
Notice that 10 = HCF(20,10) = HCF(110,20) = HCF(350,110) = HCF(810,350) = HCF(7640,810) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 6121 > 10, we apply the division lemma to 6121 and 10, to get
6121 = 10 x 612 + 1
Step 2: Since the reminder 10 ≠ 0, we apply division lemma to 1 and 10, to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 10 and 6121 is 1
Notice that 1 = HCF(10,1) = HCF(6121,10) .
