HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 746, 878 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 746, 878 is 2 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 746, 878 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 746, 878 is 2.
HCF(746, 878) = 2
HCF of 746, 878 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 746, 878 is 2.
Highest Common Factor of 746,878 is 2
Step 1: Since 878 > 746, we apply the division lemma to 878 and 746, to get
878 = 746 x 1 + 132
Step 2: Since the reminder 746 ≠ 0, we apply division lemma to 132 and 746, to get
746 = 132 x 5 + 86
Step 3: We consider the new divisor 132 and the new remainder 86, and apply the division lemma to get
132 = 86 x 1 + 46
We consider the new divisor 86 and the new remainder 46,and apply the division lemma to get
86 = 46 x 1 + 40
We consider the new divisor 46 and the new remainder 40,and apply the division lemma to get
46 = 40 x 1 + 6
We consider the new divisor 40 and the new remainder 6,and apply the division lemma to get
40 = 6 x 6 + 4
We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get
6 = 4 x 1 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 746 and 878 is 2
Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(40,6) = HCF(46,40) = HCF(86,46) = HCF(132,86) = HCF(746,132) = HCF(878,746) .
