HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 543, 996 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 543, 996 is 3 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, 543, 996 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, 543, 996 is 3.
HCF(780, 543, 996) = 3
HCF of 780, 543, 996 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, 543, 996 is 3.
Highest Common Factor of 780,543,996 is 3
Step 1: Since 780 > 543, we apply the division lemma to 780 and 543, to get
780 = 543 x 1 + 237
Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 237 and 543, to get
543 = 237 x 2 + 69
Step 3: We consider the new divisor 237 and the new remainder 69, and apply the division lemma to get
237 = 69 x 3 + 30
We consider the new divisor 69 and the new remainder 30,and apply the division lemma to get
69 = 30 x 2 + 9
We consider the new divisor 30 and the new remainder 9,and apply the division lemma to get
30 = 9 x 3 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 780 and 543 is 3
Notice that 3 = HCF(9,3) = HCF(30,9) = HCF(69,30) = HCF(237,69) = HCF(543,237) = HCF(780,543) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 996 > 3, we apply the division lemma to 996 and 3, to get
996 = 3 x 332 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 996 is 3
Notice that 3 = HCF(996,3) .
