HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 72456 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 72456 is 12 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, 72456 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, 72456 is 12.
HCF(780, 72456) = 12
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 72456 is 12.
Step 1: Since 72456 > 780, we apply the division lemma to 72456 and 780, to get
72456 = 780 x 92 + 696
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 696 and 780, to get
780 = 696 x 1 + 84
Step 3: We consider the new divisor 696 and the new remainder 84, and apply the division lemma to get
696 = 84 x 8 + 24
We consider the new divisor 84 and the new remainder 24,and apply the division lemma to get
84 = 24 x 3 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 780 and 72456 is 12
Notice that 12 = HCF(24,12) = HCF(84,24) = HCF(696,84) = HCF(780,696) = HCF(72456,780) .
Here are some samples of HCF using Euclid's Algorithm calculations.
