HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 717, 390 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 717, 390 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 717, 390 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 717, 390 is 3.
HCF(717, 390) = 3
HCF of 717, 390 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 717, 390 is 3.
Highest Common Factor of 717,390 is 3
Step 1: Since 717 > 390, we apply the division lemma to 717 and 390, to get
717 = 390 x 1 + 327
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 327 and 390, to get
390 = 327 x 1 + 63
Step 3: We consider the new divisor 327 and the new remainder 63, and apply the division lemma to get
327 = 63 x 5 + 12
We consider the new divisor 63 and the new remainder 12,and apply the division lemma to get
63 = 12 x 5 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 717 and 390 is 3
Notice that 3 = HCF(12,3) = HCF(63,12) = HCF(327,63) = HCF(390,327) = HCF(717,390) .
