HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 695, 937, 773, 978 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 695, 937, 773, 978 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 695, 937, 773, 978 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 695, 937, 773, 978 is 1.
HCF(695, 937, 773, 978) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 695, 937, 773, 978 is 1.
Step 1: Since 937 > 695, we apply the division lemma to 937 and 695, to get
937 = 695 x 1 + 242
Step 2: Since the reminder 695 ≠ 0, we apply division lemma to 242 and 695, to get
695 = 242 x 2 + 211
Step 3: We consider the new divisor 242 and the new remainder 211, and apply the division lemma to get
242 = 211 x 1 + 31
We consider the new divisor 211 and the new remainder 31,and apply the division lemma to get
211 = 31 x 6 + 25
We consider the new divisor 31 and the new remainder 25,and apply the division lemma to get
31 = 25 x 1 + 6
We consider the new divisor 25 and the new remainder 6,and apply the division lemma to get
25 = 6 x 4 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 695 and 937 is 1
Notice that 1 = HCF(6,1) = HCF(25,6) = HCF(31,25) = HCF(211,31) = HCF(242,211) = HCF(695,242) = HCF(937,695) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 773 > 1, we apply the division lemma to 773 and 1, to get
773 = 1 x 773 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 773 is 1
Notice that 1 = HCF(773,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 978 > 1, we apply the division lemma to 978 and 1, to get
978 = 1 x 978 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 978 is 1
Notice that 1 = HCF(978,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
