HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 891, 742 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 891, 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 891, 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 891, 742 is 1.
HCF(891, 742) = 1
HCF of 891, 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 891, 742 is 1.
Highest Common Factor of 891,742 is 1
Step 1: Since 891 > 742, we apply the division lemma to 891 and 742, to get
891 = 742 x 1 + 149
Step 2: Since the reminder 742 ≠ 0, we apply division lemma to 149 and 742, to get
742 = 149 x 4 + 146
Step 3: We consider the new divisor 149 and the new remainder 146, and apply the division lemma to get
149 = 146 x 1 + 3
We consider the new divisor 146 and the new remainder 3,and apply the division lemma to get
146 = 3 x 48 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 891 and 742 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(146,3) = HCF(149,146) = HCF(742,149) = HCF(891,742) .
