HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 657, 476, 189 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 657, 476, 189 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 657, 476, 189 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 657, 476, 189 is 1.
HCF(657, 476, 189) = 1
HCF of 657, 476, 189 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 657, 476, 189 is 1.
Highest Common Factor of 657,476,189 is 1
Step 1: Since 657 > 476, we apply the division lemma to 657 and 476, to get
657 = 476 x 1 + 181
Step 2: Since the reminder 476 ≠ 0, we apply division lemma to 181 and 476, to get
476 = 181 x 2 + 114
Step 3: We consider the new divisor 181 and the new remainder 114, and apply the division lemma to get
181 = 114 x 1 + 67
We consider the new divisor 114 and the new remainder 67,and apply the division lemma to get
114 = 67 x 1 + 47
We consider the new divisor 67 and the new remainder 47,and apply the division lemma to get
67 = 47 x 1 + 20
We consider the new divisor 47 and the new remainder 20,and apply the division lemma to get
47 = 20 x 2 + 7
We consider the new divisor 20 and the new remainder 7,and apply the division lemma to get
20 = 7 x 2 + 6
We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get
7 = 6 x 1 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 657 and 476 is 1
Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(20,7) = HCF(47,20) = HCF(67,47) = HCF(114,67) = HCF(181,114) = HCF(476,181) = HCF(657,476) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 189 > 1, we apply the division lemma to 189 and 1, to get
189 = 1 x 189 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 189 is 1
Notice that 1 = HCF(189,1) .
