HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 25, 77, 943, 968 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 25, 77, 943, 968 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 25, 77, 943, 968 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 25, 77, 943, 968 is 1.
HCF(25, 77, 943, 968) = 1
HCF of 25, 77, 943, 968 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 25, 77, 943, 968 is 1.
Highest Common Factor of 25,77,943,968 is 1
Step 1: Since 77 > 25, we apply the division lemma to 77 and 25, to get
77 = 25 x 3 + 2
Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 2 and 25, to get
25 = 2 x 12 + 1
Step 3: 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 25 and 77 is 1
Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(77,25) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 943 > 1, we apply the division lemma to 943 and 1, to get
943 = 1 x 943 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 943 is 1
Notice that 1 = HCF(943,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 968 > 1, we apply the division lemma to 968 and 1, to get
968 = 1 x 968 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 968 is 1
Notice that 1 = HCF(968,1) .
