HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 198, 235 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 198, 235 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 780, 198, 235 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 780, 198, 235 is 1.
HCF(780, 198, 235) = 1
HCF of 780, 198, 235 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 198, 235 is 1.
Highest Common Factor of 780,198,235 is 1
Step 1: Since 780 > 198, we apply the division lemma to 780 and 198, to get
780 = 198 x 3 + 186
Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 186 and 198, to get
198 = 186 x 1 + 12
Step 3: We consider the new divisor 186 and the new remainder 12, and apply the division lemma to get
186 = 12 x 15 + 6
We consider the new divisor 12 and the new remainder 6, and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 780 and 198 is 6
Notice that 6 = HCF(12,6) = HCF(186,12) = HCF(198,186) = HCF(780,198) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 235 > 6, we apply the division lemma to 235 and 6, to get
235 = 6 x 39 + 1
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 1 and 6, to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6 and 235 is 1
Notice that 1 = HCF(6,1) = HCF(235,6) .
