HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 780, 563 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 780, 563 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 780, 563 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 780, 563 is 1.
HCF(780, 563) = 1
HCF of 780, 563 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 780, 563 is 1.
Highest Common Factor of 780,563 is 1
Step 1: Since 780 > 563, we apply the division lemma to 780 and 563, to get
780 = 563 x 1 + 217
Step 2: Since the reminder 563 ≠ 0, we apply division lemma to 217 and 563, to get
563 = 217 x 2 + 129
Step 3: We consider the new divisor 217 and the new remainder 129, and apply the division lemma to get
217 = 129 x 1 + 88
We consider the new divisor 129 and the new remainder 88,and apply the division lemma to get
129 = 88 x 1 + 41
We consider the new divisor 88 and the new remainder 41,and apply the division lemma to get
88 = 41 x 2 + 6
We consider the new divisor 41 and the new remainder 6,and apply the division lemma to get
41 = 6 x 6 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 780 and 563 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(41,6) = HCF(88,41) = HCF(129,88) = HCF(217,129) = HCF(563,217) = HCF(780,563) .
