HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 781, 962, 433 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 781, 962, 433 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 781, 962, 433 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 781, 962, 433 is 1.
HCF(781, 962, 433) = 1
HCF of 781, 962, 433 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 781, 962, 433 is 1.
Highest Common Factor of 781,962,433 is 1
Step 1: Since 962 > 781, we apply the division lemma to 962 and 781, to get
962 = 781 x 1 + 181
Step 2: Since the reminder 781 ≠ 0, we apply division lemma to 181 and 781, to get
781 = 181 x 4 + 57
Step 3: We consider the new divisor 181 and the new remainder 57, and apply the division lemma to get
181 = 57 x 3 + 10
We consider the new divisor 57 and the new remainder 10,and apply the division lemma to get
57 = 10 x 5 + 7
We consider the new divisor 10 and the new remainder 7,and apply the division lemma to get
10 = 7 x 1 + 3
We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get
7 = 3 x 2 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 781 and 962 is 1
Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(10,7) = HCF(57,10) = HCF(181,57) = HCF(781,181) = HCF(962,781) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 433 > 1, we apply the division lemma to 433 and 1, to get
433 = 1 x 433 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 433 is 1
Notice that 1 = HCF(433,1) .
