HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 740, 76, 789 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 740, 76, 789 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 740, 76, 789 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 740, 76, 789 is 1.
HCF(740, 76, 789) = 1
HCF of 740, 76, 789 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 740, 76, 789 is 1.
Highest Common Factor of 740,76,789 is 1
Step 1: Since 740 > 76, we apply the division lemma to 740 and 76, to get
740 = 76 x 9 + 56
Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 56 and 76, to get
76 = 56 x 1 + 20
Step 3: We consider the new divisor 56 and the new remainder 20, and apply the division lemma to get
56 = 20 x 2 + 16
We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get
20 = 16 x 1 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 740 and 76 is 4
Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(56,20) = HCF(76,56) = HCF(740,76) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 789 > 4, we apply the division lemma to 789 and 4, to get
789 = 4 x 197 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, 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 4 and 789 is 1
Notice that 1 = HCF(4,1) = HCF(789,4) .
