HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 791, 504 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 791, 504 is 7 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 791, 504 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 791, 504 is 7.
HCF(791, 504) = 7
HCF of 791, 504 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 791, 504 is 7.
Highest Common Factor of 791,504 is 7
Step 1: Since 791 > 504, we apply the division lemma to 791 and 504, to get
791 = 504 x 1 + 287
Step 2: Since the reminder 504 ≠ 0, we apply division lemma to 287 and 504, to get
504 = 287 x 1 + 217
Step 3: We consider the new divisor 287 and the new remainder 217, and apply the division lemma to get
287 = 217 x 1 + 70
We consider the new divisor 217 and the new remainder 70,and apply the division lemma to get
217 = 70 x 3 + 7
We consider the new divisor 70 and the new remainder 7,and apply the division lemma to get
70 = 7 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 791 and 504 is 7
Notice that 7 = HCF(70,7) = HCF(217,70) = HCF(287,217) = HCF(504,287) = HCF(791,504) .
