HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 648 i.e. 27 the largest integer that leaves a remainder zero for all numbers.
HCF of 783, 648 is 27 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 783, 648 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 783, 648 is 27.
HCF(783, 648) = 27
HCF of 783, 648 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 783, 648 is 27.
Highest Common Factor of 783,648 is 27
Step 1: Since 783 > 648, we apply the division lemma to 783 and 648, to get
783 = 648 x 1 + 135
Step 2: Since the reminder 648 ≠ 0, we apply division lemma to 135 and 648, to get
648 = 135 x 4 + 108
Step 3: We consider the new divisor 135 and the new remainder 108, and apply the division lemma to get
135 = 108 x 1 + 27
We consider the new divisor 108 and the new remainder 27, and apply the division lemma to get
108 = 27 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 783 and 648 is 27
Notice that 27 = HCF(108,27) = HCF(135,108) = HCF(648,135) = HCF(783,648) .
