HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 218, 179 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 218, 179 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, 218, 179 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, 218, 179 is 1.
HCF(789, 218, 179) = 1
HCF of 789, 218, 179 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, 218, 179 is 1.
Highest Common Factor of 789,218,179 is 1
Step 1: Since 789 > 218, we apply the division lemma to 789 and 218, to get
789 = 218 x 3 + 135
Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 135 and 218, to get
218 = 135 x 1 + 83
Step 3: We consider the new divisor 135 and the new remainder 83, and apply the division lemma to get
135 = 83 x 1 + 52
We consider the new divisor 83 and the new remainder 52,and apply the division lemma to get
83 = 52 x 1 + 31
We consider the new divisor 52 and the new remainder 31,and apply the division lemma to get
52 = 31 x 1 + 21
We consider the new divisor 31 and the new remainder 21,and apply the division lemma to get
31 = 21 x 1 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma 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 789 and 218 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(31,21) = HCF(52,31) = HCF(83,52) = HCF(135,83) = HCF(218,135) = HCF(789,218) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 179 > 1, we apply the division lemma to 179 and 1, to get
179 = 1 x 179 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 179 is 1
Notice that 1 = HCF(179,1) .
