HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 814, 900 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 814, 900 is 2 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, 814, 900 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, 814, 900 is 2.
HCF(636, 814, 900) = 2
HCF of 636, 814, 900 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, 814, 900 is 2.
Highest Common Factor of 636,814,900 is 2
Step 1: Since 814 > 636, we apply the division lemma to 814 and 636, to get
814 = 636 x 1 + 178
Step 2: Since the reminder 636 ≠ 0, we apply division lemma to 178 and 636, to get
636 = 178 x 3 + 102
Step 3: We consider the new divisor 178 and the new remainder 102, and apply the division lemma to get
178 = 102 x 1 + 76
We consider the new divisor 102 and the new remainder 76,and apply the division lemma to get
102 = 76 x 1 + 26
We consider the new divisor 76 and the new remainder 26,and apply the division lemma to get
76 = 26 x 2 + 24
We consider the new divisor 26 and the new remainder 24,and apply the division lemma to get
26 = 24 x 1 + 2
We consider the new divisor 24 and the new remainder 2,and apply the division lemma to get
24 = 2 x 12 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 636 and 814 is 2
Notice that 2 = HCF(24,2) = HCF(26,24) = HCF(76,26) = HCF(102,76) = HCF(178,102) = HCF(636,178) = HCF(814,636) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 900 > 2, we apply the division lemma to 900 and 2, to get
900 = 2 x 450 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 900 is 2
Notice that 2 = HCF(900,2) .
