HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 747, 689, 447 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 747, 689, 447 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 747, 689, 447 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 747, 689, 447 is 1.
HCF(747, 689, 447) = 1
HCF of 747, 689, 447 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 747, 689, 447 is 1.
Highest Common Factor of 747,689,447 is 1
Step 1: Since 747 > 689, we apply the division lemma to 747 and 689, to get
747 = 689 x 1 + 58
Step 2: Since the reminder 689 ≠ 0, we apply division lemma to 58 and 689, to get
689 = 58 x 11 + 51
Step 3: We consider the new divisor 58 and the new remainder 51, and apply the division lemma to get
58 = 51 x 1 + 7
We consider the new divisor 51 and the new remainder 7,and apply the division lemma to get
51 = 7 x 7 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 747 and 689 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(51,7) = HCF(58,51) = HCF(689,58) = HCF(747,689) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 447 > 1, we apply the division lemma to 447 and 1, to get
447 = 1 x 447 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 447 is 1
Notice that 1 = HCF(447,1) .
