HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 522, 186 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 397, 522, 186 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 397, 522, 186 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 397, 522, 186 is 1.
HCF(397, 522, 186) = 1
HCF of 397, 522, 186 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 397, 522, 186 is 1.
Highest Common Factor of 397,522,186 is 1
Step 1: Since 522 > 397, we apply the division lemma to 522 and 397, to get
522 = 397 x 1 + 125
Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 125 and 397, to get
397 = 125 x 3 + 22
Step 3: We consider the new divisor 125 and the new remainder 22, and apply the division lemma to get
125 = 22 x 5 + 15
We consider the new divisor 22 and the new remainder 15,and apply the division lemma to get
22 = 15 x 1 + 7
We consider the new divisor 15 and the new remainder 7,and apply the division lemma to get
15 = 7 x 2 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 397 and 522 is 1
Notice that 1 = HCF(7,1) = HCF(15,7) = HCF(22,15) = HCF(125,22) = HCF(397,125) = HCF(522,397) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 186 > 1, we apply the division lemma to 186 and 1, to get
186 = 1 x 186 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 186 is 1
Notice that 1 = HCF(186,1) .
