HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 810, 747, 339 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 810, 747, 339 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 810, 747, 339 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 810, 747, 339 is 3.
HCF(810, 747, 339) = 3
HCF of 810, 747, 339 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 810, 747, 339 is 3.
Highest Common Factor of 810,747,339 is 3
Step 1: Since 810 > 747, we apply the division lemma to 810 and 747, to get
810 = 747 x 1 + 63
Step 2: Since the reminder 747 ≠ 0, we apply division lemma to 63 and 747, to get
747 = 63 x 11 + 54
Step 3: We consider the new divisor 63 and the new remainder 54, and apply the division lemma to get
63 = 54 x 1 + 9
We consider the new divisor 54 and the new remainder 9, and apply the division lemma to get
54 = 9 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 810 and 747 is 9
Notice that 9 = HCF(54,9) = HCF(63,54) = HCF(747,63) = HCF(810,747) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 339 > 9, we apply the division lemma to 339 and 9, to get
339 = 9 x 37 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 339 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(339,9) .
