HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 940, 340, 51 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 940, 340, 51 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 940, 340, 51 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 940, 340, 51 is 1.
HCF(940, 340, 51) = 1
HCF of 940, 340, 51 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 940, 340, 51 is 1.
Highest Common Factor of 940,340,51 is 1
Step 1: Since 940 > 340, we apply the division lemma to 940 and 340, to get
940 = 340 x 2 + 260
Step 2: Since the reminder 340 ≠ 0, we apply division lemma to 260 and 340, to get
340 = 260 x 1 + 80
Step 3: We consider the new divisor 260 and the new remainder 80, and apply the division lemma to get
260 = 80 x 3 + 20
We consider the new divisor 80 and the new remainder 20, and apply the division lemma to get
80 = 20 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 940 and 340 is 20
Notice that 20 = HCF(80,20) = HCF(260,80) = HCF(340,260) = HCF(940,340) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 51 > 20, we apply the division lemma to 51 and 20, to get
51 = 20 x 2 + 11
Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 11 and 20, to get
20 = 11 x 1 + 9
Step 3: We consider the new divisor 11 and the new remainder 9, and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 20 and 51 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(51,20) .
