HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 82, 66, 790, 663 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 82, 66, 790, 663 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 82, 66, 790, 663 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 82, 66, 790, 663 is 1.
HCF(82, 66, 790, 663) = 1
HCF of 82, 66, 790, 663 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 82, 66, 790, 663 is 1.
Highest Common Factor of 82,66,790,663 is 1
Step 1: Since 82 > 66, we apply the division lemma to 82 and 66, to get
82 = 66 x 1 + 16
Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 16 and 66, to get
66 = 16 x 4 + 2
Step 3: We consider the new divisor 16 and the new remainder 2, and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 82 and 66 is 2
Notice that 2 = HCF(16,2) = HCF(66,16) = HCF(82,66) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 790 > 2, we apply the division lemma to 790 and 2, to get
790 = 2 x 395 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 790 is 2
Notice that 2 = HCF(790,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 663 > 2, we apply the division lemma to 663 and 2, to get
663 = 2 x 331 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 663 is 1
Notice that 1 = HCF(2,1) = HCF(663,2) .
