HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 681, 477 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 942, 681, 477 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 942, 681, 477 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 942, 681, 477 is 3.
HCF(942, 681, 477) = 3
HCF of 942, 681, 477 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 942, 681, 477 is 3.
Highest Common Factor of 942,681,477 is 3
Step 1: Since 942 > 681, we apply the division lemma to 942 and 681, to get
942 = 681 x 1 + 261
Step 2: Since the reminder 681 ≠ 0, we apply division lemma to 261 and 681, to get
681 = 261 x 2 + 159
Step 3: We consider the new divisor 261 and the new remainder 159, and apply the division lemma to get
261 = 159 x 1 + 102
We consider the new divisor 159 and the new remainder 102,and apply the division lemma to get
159 = 102 x 1 + 57
We consider the new divisor 102 and the new remainder 57,and apply the division lemma to get
102 = 57 x 1 + 45
We consider the new divisor 57 and the new remainder 45,and apply the division lemma to get
57 = 45 x 1 + 12
We consider the new divisor 45 and the new remainder 12,and apply the division lemma to get
45 = 12 x 3 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 942 and 681 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(45,12) = HCF(57,45) = HCF(102,57) = HCF(159,102) = HCF(261,159) = HCF(681,261) = HCF(942,681) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 477 > 3, we apply the division lemma to 477 and 3, to get
477 = 3 x 159 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 477 is 3
Notice that 3 = HCF(477,3) .
