HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 865, 274, 648 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 865, 274, 648 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 865, 274, 648 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 865, 274, 648 is 1.
HCF(865, 274, 648) = 1
HCF of 865, 274, 648 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 865, 274, 648 is 1.
Highest Common Factor of 865,274,648 is 1
Step 1: Since 865 > 274, we apply the division lemma to 865 and 274, to get
865 = 274 x 3 + 43
Step 2: Since the reminder 274 ≠ 0, we apply division lemma to 43 and 274, to get
274 = 43 x 6 + 16
Step 3: We consider the new divisor 43 and the new remainder 16, and apply the division lemma to get
43 = 16 x 2 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 865 and 274 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(43,16) = HCF(274,43) = HCF(865,274) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 648 > 1, we apply the division lemma to 648 and 1, to get
648 = 1 x 648 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 648 is 1
Notice that 1 = HCF(648,1) .
