HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 159, 636, 939 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 159, 636, 939 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 159, 636, 939 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 159, 636, 939 is 3.
HCF(159, 636, 939) = 3
HCF of 159, 636, 939 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 159, 636, 939 is 3.
Highest Common Factor of 159,636,939 is 3
Step 1: Since 636 > 159, we apply the division lemma to 636 and 159, to get
636 = 159 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 159, the HCF of 159 and 636 is 159
Notice that 159 = HCF(636,159) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 939 > 159, we apply the division lemma to 939 and 159, to get
939 = 159 x 5 + 144
Step 2: Since the reminder 159 ≠ 0, we apply division lemma to 144 and 159, to get
159 = 144 x 1 + 15
Step 3: We consider the new divisor 144 and the new remainder 15, and apply the division lemma to get
144 = 15 x 9 + 9
We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get
15 = 9 x 1 + 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 159 and 939 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(144,15) = HCF(159,144) = HCF(939,159) .
