HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 939, 477 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 939, 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 939, 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 939, 477 is 3.
HCF(939, 477) = 3
HCF of 939, 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 939, 477 is 3.
Highest Common Factor of 939,477 is 3
Step 1: Since 939 > 477, we apply the division lemma to 939 and 477, to get
939 = 477 x 1 + 462
Step 2: Since the reminder 477 ≠ 0, we apply division lemma to 462 and 477, to get
477 = 462 x 1 + 15
Step 3: We consider the new divisor 462 and the new remainder 15, and apply the division lemma to get
462 = 15 x 30 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 939 and 477 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(462,15) = HCF(477,462) = HCF(939,477) .
