HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 80, 291, 742 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 80, 291, 742 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 80, 291, 742 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 80, 291, 742 is 1.
HCF(80, 291, 742) = 1
HCF of 80, 291, 742 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 80, 291, 742 is 1.
Highest Common Factor of 80,291,742 is 1
Step 1: Since 291 > 80, we apply the division lemma to 291 and 80, to get
291 = 80 x 3 + 51
Step 2: Since the reminder 80 ≠ 0, we apply division lemma to 51 and 80, to get
80 = 51 x 1 + 29
Step 3: We consider the new divisor 51 and the new remainder 29, and apply the division lemma to get
51 = 29 x 1 + 22
We consider the new divisor 29 and the new remainder 22,and apply the division lemma to get
29 = 22 x 1 + 7
We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get
22 = 7 x 3 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 80 and 291 is 1
Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(29,22) = HCF(51,29) = HCF(80,51) = HCF(291,80) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 742 > 1, we apply the division lemma to 742 and 1, to get
742 = 1 x 742 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 742 is 1
Notice that 1 = HCF(742,1) .
