HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 559, 557 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 559, 557 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 636, 559, 557 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 636, 559, 557 is 1.
HCF(636, 559, 557) = 1
HCF of 636, 559, 557 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 636, 559, 557 is 1.
Highest Common Factor of 636,559,557 is 1
Step 1: Since 636 > 559, we apply the division lemma to 636 and 559, to get
636 = 559 x 1 + 77
Step 2: Since the reminder 559 ≠ 0, we apply division lemma to 77 and 559, to get
559 = 77 x 7 + 20
Step 3: We consider the new divisor 77 and the new remainder 20, and apply the division lemma to get
77 = 20 x 3 + 17
We consider the new divisor 20 and the new remainder 17,and apply the division lemma to get
20 = 17 x 1 + 3
We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get
17 = 3 x 5 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 636 and 559 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(77,20) = HCF(559,77) = HCF(636,559) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 557 > 1, we apply the division lemma to 557 and 1, to get
557 = 1 x 557 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 557 is 1
Notice that 1 = HCF(557,1) .
