HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 235, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 235, 80 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 782, 235, 80 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 782, 235, 80 is 1.
HCF(782, 235, 80) = 1
HCF of 782, 235, 80 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 235, 80 is 1.
Highest Common Factor of 782,235,80 is 1
Step 1: Since 782 > 235, we apply the division lemma to 782 and 235, to get
782 = 235 x 3 + 77
Step 2: Since the reminder 235 ≠ 0, we apply division lemma to 77 and 235, to get
235 = 77 x 3 + 4
Step 3: We consider the new divisor 77 and the new remainder 4, and apply the division lemma to get
77 = 4 x 19 + 1
We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 782 and 235 is 1
Notice that 1 = HCF(4,1) = HCF(77,4) = HCF(235,77) = HCF(782,235) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 80 > 1, we apply the division lemma to 80 and 1, to get
80 = 1 x 80 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 80 is 1
Notice that 1 = HCF(80,1) .
