HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 787, 932 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 787, 932 is 1 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 787, 932 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 787, 932 is 1.
HCF(787, 932) = 1
HCF of 787, 932 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 787, 932 is 1.
Highest Common Factor of 787,932 is 1
Step 1: Since 932 > 787, we apply the division lemma to 932 and 787, to get
932 = 787 x 1 + 145
Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 145 and 787, to get
787 = 145 x 5 + 62
Step 3: We consider the new divisor 145 and the new remainder 62, and apply the division lemma to get
145 = 62 x 2 + 21
We consider the new divisor 62 and the new remainder 21,and apply the division lemma to get
62 = 21 x 2 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 787 and 932 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(62,21) = HCF(145,62) = HCF(787,145) = HCF(932,787) .
