HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 156, 201, 426 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 156, 201, 426 is 3 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 156, 201, 426 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 156, 201, 426 is 3.
HCF(156, 201, 426) = 3
HCF of 156, 201, 426 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 156, 201, 426 is 3.
Highest Common Factor of 156,201,426 is 3
Step 1: Since 201 > 156, we apply the division lemma to 201 and 156, to get
201 = 156 x 1 + 45
Step 2: Since the reminder 156 ≠ 0, we apply division lemma to 45 and 156, to get
156 = 45 x 3 + 21
Step 3: We consider the new divisor 45 and the new remainder 21, and apply the division lemma to get
45 = 21 x 2 + 3
We consider the new divisor 21 and the new remainder 3, and apply the division lemma to get
21 = 3 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 156 and 201 is 3
Notice that 3 = HCF(21,3) = HCF(45,21) = HCF(156,45) = HCF(201,156) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 426 > 3, we apply the division lemma to 426 and 3, to get
426 = 3 x 142 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 426 is 3
Notice that 3 = HCF(426,3) .
