HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 714, 682 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 714, 682 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 789, 714, 682 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 789, 714, 682 is 1.
HCF(789, 714, 682) = 1
HCF of 789, 714, 682 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 789, 714, 682 is 1.
Highest Common Factor of 789,714,682 is 1
Step 1: Since 789 > 714, we apply the division lemma to 789 and 714, to get
789 = 714 x 1 + 75
Step 2: Since the reminder 714 ≠ 0, we apply division lemma to 75 and 714, to get
714 = 75 x 9 + 39
Step 3: We consider the new divisor 75 and the new remainder 39, and apply the division lemma to get
75 = 39 x 1 + 36
We consider the new divisor 39 and the new remainder 36,and apply the division lemma to get
39 = 36 x 1 + 3
We consider the new divisor 36 and the new remainder 3,and apply the division lemma to get
36 = 3 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 789 and 714 is 3
Notice that 3 = HCF(36,3) = HCF(39,36) = HCF(75,39) = HCF(714,75) = HCF(789,714) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 682 > 3, we apply the division lemma to 682 and 3, to get
682 = 3 x 227 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 682 is 1
Notice that 1 = HCF(3,1) = HCF(682,3) .
