HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 636, 789, 324, 67 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 636, 789, 324, 67 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, 789, 324, 67 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, 789, 324, 67 is 1.
HCF(636, 789, 324, 67) = 1
HCF of 636, 789, 324, 67 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, 789, 324, 67 is 1.
Highest Common Factor of 636,789,324,67 is 1
Step 1: Since 789 > 636, we apply the division lemma to 789 and 636, to get
789 = 636 x 1 + 153
Step 2: Since the reminder 636 ≠ 0, we apply division lemma to 153 and 636, to get
636 = 153 x 4 + 24
Step 3: We consider the new divisor 153 and the new remainder 24, and apply the division lemma to get
153 = 24 x 6 + 9
We consider the new divisor 24 and the new remainder 9,and apply the division lemma to get
24 = 9 x 2 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 636 and 789 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(24,9) = HCF(153,24) = HCF(636,153) = HCF(789,636) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 324 > 3, we apply the division lemma to 324 and 3, to get
324 = 3 x 108 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 324 is 3
Notice that 3 = HCF(324,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 67 > 3, we apply the division lemma to 67 and 3, to get
67 = 3 x 22 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, 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 3 and 67 is 1
Notice that 1 = HCF(3,1) = HCF(67,3) .
