HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 607, 709, 243 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 607, 709, 243 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 607, 709, 243 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 607, 709, 243 is 1.
HCF(607, 709, 243) = 1
HCF of 607, 709, 243 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 607, 709, 243 is 1.
Highest Common Factor of 607,709,243 is 1
Step 1: Since 709 > 607, we apply the division lemma to 709 and 607, to get
709 = 607 x 1 + 102
Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 102 and 607, to get
607 = 102 x 5 + 97
Step 3: We consider the new divisor 102 and the new remainder 97, and apply the division lemma to get
102 = 97 x 1 + 5
We consider the new divisor 97 and the new remainder 5,and apply the division lemma to get
97 = 5 x 19 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 607 and 709 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(97,5) = HCF(102,97) = HCF(607,102) = HCF(709,607) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 243 > 1, we apply the division lemma to 243 and 1, to get
243 = 1 x 243 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 243 is 1
Notice that 1 = HCF(243,1) .
