HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 728, 390 i.e. 26 the largest integer that leaves a remainder zero for all numbers.
HCF of 728, 390 is 26 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 728, 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 728, 390 is 26.
HCF(728, 390) = 26
HCF of 728, 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 728, 390 is 26.
Highest Common Factor of 728,390 is 26
Step 1: Since 728 > 390, we apply the division lemma to 728 and 390, to get
728 = 390 x 1 + 338
Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 338 and 390, to get
390 = 338 x 1 + 52
Step 3: We consider the new divisor 338 and the new remainder 52, and apply the division lemma to get
338 = 52 x 6 + 26
We consider the new divisor 52 and the new remainder 26, and apply the division lemma to get
52 = 26 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 26, the HCF of 728 and 390 is 26
Notice that 26 = HCF(52,26) = HCF(338,52) = HCF(390,338) = HCF(728,390) .
