HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 939, 480, 126 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 939, 480, 126 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, 480, 126 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, 480, 126 is 3.
HCF(939, 480, 126) = 3
HCF of 939, 480, 126 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, 480, 126 is 3.
Highest Common Factor of 939,480,126 is 3
Step 1: Since 939 > 480, we apply the division lemma to 939 and 480, to get
939 = 480 x 1 + 459
Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 459 and 480, to get
480 = 459 x 1 + 21
Step 3: We consider the new divisor 459 and the new remainder 21, and apply the division lemma to get
459 = 21 x 21 + 18
We consider the new divisor 21 and the new remainder 18,and apply the division lemma to get
21 = 18 x 1 + 3
We consider the new divisor 18 and the new remainder 3,and apply the division lemma to get
18 = 3 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 939 and 480 is 3
Notice that 3 = HCF(18,3) = HCF(21,18) = HCF(459,21) = HCF(480,459) = HCF(939,480) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 126 > 3, we apply the division lemma to 126 and 3, to get
126 = 3 x 42 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 126 is 3
Notice that 3 = HCF(126,3) .
