HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 783, 2157 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 783, 2157 is 3 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, 2157 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, 2157 is 3.
HCF(783, 2157) = 3
HCF of 783, 2157 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, 2157 is 3.
Highest Common Factor of 783,2157 is 3
Step 1: Since 2157 > 783, we apply the division lemma to 2157 and 783, to get
2157 = 783 x 2 + 591
Step 2: Since the reminder 783 ≠ 0, we apply division lemma to 591 and 783, to get
783 = 591 x 1 + 192
Step 3: We consider the new divisor 591 and the new remainder 192, and apply the division lemma to get
591 = 192 x 3 + 15
We consider the new divisor 192 and the new remainder 15,and apply the division lemma to get
192 = 15 x 12 + 12
We consider the new divisor 15 and the new remainder 12,and apply the division lemma to get
15 = 12 x 1 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 783 and 2157 is 3
Notice that 3 = HCF(12,3) = HCF(15,12) = HCF(192,15) = HCF(591,192) = HCF(783,591) = HCF(2157,783) .
