HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1620, 7317 i.e. 27 the largest integer that leaves a remainder zero for all numbers.
HCF of 1620, 7317 is 27 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 1620, 7317 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 1620, 7317 is 27.
HCF(1620, 7317) = 27
HCF of 1620, 7317 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1620, 7317 is 27.
Highest Common Factor of 1620,7317 is 27
Step 1: Since 7317 > 1620, we apply the division lemma to 7317 and 1620, to get
7317 = 1620 x 4 + 837
Step 2: Since the reminder 1620 ≠ 0, we apply division lemma to 837 and 1620, to get
1620 = 837 x 1 + 783
Step 3: We consider the new divisor 837 and the new remainder 783, and apply the division lemma to get
837 = 783 x 1 + 54
We consider the new divisor 783 and the new remainder 54,and apply the division lemma to get
783 = 54 x 14 + 27
We consider the new divisor 54 and the new remainder 27,and apply the division lemma to get
54 = 27 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 27, the HCF of 1620 and 7317 is 27
Notice that 27 = HCF(54,27) = HCF(783,54) = HCF(837,783) = HCF(1620,837) = HCF(7317,1620) .
