HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 266, 716, 778 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 266, 716, 778 is 2 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 266, 716, 778 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 266, 716, 778 is 2.
HCF(266, 716, 778) = 2
HCF of 266, 716, 778 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 266, 716, 778 is 2.
Highest Common Factor of 266,716,778 is 2
Step 1: Since 716 > 266, we apply the division lemma to 716 and 266, to get
716 = 266 x 2 + 184
Step 2: Since the reminder 266 ≠ 0, we apply division lemma to 184 and 266, to get
266 = 184 x 1 + 82
Step 3: We consider the new divisor 184 and the new remainder 82, and apply the division lemma to get
184 = 82 x 2 + 20
We consider the new divisor 82 and the new remainder 20,and apply the division lemma to get
82 = 20 x 4 + 2
We consider the new divisor 20 and the new remainder 2,and apply the division lemma to get
20 = 2 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 266 and 716 is 2
Notice that 2 = HCF(20,2) = HCF(82,20) = HCF(184,82) = HCF(266,184) = HCF(716,266) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 778 > 2, we apply the division lemma to 778 and 2, to get
778 = 2 x 389 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 778 is 2
Notice that 2 = HCF(778,2) .
