HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 943, 3138, 2685 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 943, 3138, 2685 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 943, 3138, 2685 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 943, 3138, 2685 is 1.
HCF(943, 3138, 2685) = 1
HCF of 943, 3138, 2685 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 943, 3138, 2685 is 1.
Highest Common Factor of 943,3138,2685 is 1
Step 1: Since 3138 > 943, we apply the division lemma to 3138 and 943, to get
3138 = 943 x 3 + 309
Step 2: Since the reminder 943 ≠ 0, we apply division lemma to 309 and 943, to get
943 = 309 x 3 + 16
Step 3: We consider the new divisor 309 and the new remainder 16, and apply the division lemma to get
309 = 16 x 19 + 5
We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 943 and 3138 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(309,16) = HCF(943,309) = HCF(3138,943) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 2685 > 1, we apply the division lemma to 2685 and 1, to get
2685 = 1 x 2685 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 2685 is 1
Notice that 1 = HCF(2685,1) .
