HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 905 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 783, 905 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 783, 905 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, 905 is 1.
HCF(783, 905) = 1
HCF of 783, 905 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, 905 is 1.
Highest Common Factor of 783,905 is 1
Step 1: Since 905 > 783, we apply the division lemma to 905 and 783, to get
905 = 783 x 1 + 122
Step 2: Since the reminder 783 ≠ 0, we apply division lemma to 122 and 783, to get
783 = 122 x 6 + 51
Step 3: We consider the new divisor 122 and the new remainder 51, and apply the division lemma to get
122 = 51 x 2 + 20
We consider the new divisor 51 and the new remainder 20,and apply the division lemma to get
51 = 20 x 2 + 11
We consider the new divisor 20 and the new remainder 11,and apply the division lemma to get
20 = 11 x 1 + 9
We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get
11 = 9 x 1 + 2
We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get
9 = 2 x 4 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 783 and 905 is 1
Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(20,11) = HCF(51,20) = HCF(122,51) = HCF(783,122) = HCF(905,783) .
