HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 305, 636 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 558, 305, 636 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 558, 305, 636 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 558, 305, 636 is 1.
HCF(558, 305, 636) = 1
HCF of 558, 305, 636 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 558, 305, 636 is 1.
Highest Common Factor of 558,305,636 is 1
Step 1: Since 558 > 305, we apply the division lemma to 558 and 305, to get
558 = 305 x 1 + 253
Step 2: Since the reminder 305 ≠ 0, we apply division lemma to 253 and 305, to get
305 = 253 x 1 + 52
Step 3: We consider the new divisor 253 and the new remainder 52, and apply the division lemma to get
253 = 52 x 4 + 45
We consider the new divisor 52 and the new remainder 45,and apply the division lemma to get
52 = 45 x 1 + 7
We consider the new divisor 45 and the new remainder 7,and apply the division lemma to get
45 = 7 x 6 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 558 and 305 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(45,7) = HCF(52,45) = HCF(253,52) = HCF(305,253) = HCF(558,305) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 636 > 1, we apply the division lemma to 636 and 1, to get
636 = 1 x 636 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 636 is 1
Notice that 1 = HCF(636,1) .
