HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 743, 939, 76 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 743, 939, 76 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 743, 939, 76 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 743, 939, 76 is 1.
HCF(743, 939, 76) = 1
HCF of 743, 939, 76 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 743, 939, 76 is 1.
Highest Common Factor of 743,939,76 is 1
Step 1: Since 939 > 743, we apply the division lemma to 939 and 743, to get
939 = 743 x 1 + 196
Step 2: Since the reminder 743 ≠ 0, we apply division lemma to 196 and 743, to get
743 = 196 x 3 + 155
Step 3: We consider the new divisor 196 and the new remainder 155, and apply the division lemma to get
196 = 155 x 1 + 41
We consider the new divisor 155 and the new remainder 41,and apply the division lemma to get
155 = 41 x 3 + 32
We consider the new divisor 41 and the new remainder 32,and apply the division lemma to get
41 = 32 x 1 + 9
We consider the new divisor 32 and the new remainder 9,and apply the division lemma to get
32 = 9 x 3 + 5
We consider the new divisor 9 and the new remainder 5,and apply the division lemma to get
9 = 5 x 1 + 4
We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get
5 = 4 x 1 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 743 and 939 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(9,5) = HCF(32,9) = HCF(41,32) = HCF(155,41) = HCF(196,155) = HCF(743,196) = HCF(939,743) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 76 > 1, we apply the division lemma to 76 and 1, to get
76 = 1 x 76 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 76 is 1
Notice that 1 = HCF(76,1) .
