HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 6789, 1720 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 6789, 1720 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 6789, 1720 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 6789, 1720 is 1.
HCF(6789, 1720) = 1
HCF of 6789, 1720 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 6789, 1720 is 1.
Highest Common Factor of 6789,1720 is 1
Step 1: Since 6789 > 1720, we apply the division lemma to 6789 and 1720, to get
6789 = 1720 x 3 + 1629
Step 2: Since the reminder 1720 ≠ 0, we apply division lemma to 1629 and 1720, to get
1720 = 1629 x 1 + 91
Step 3: We consider the new divisor 1629 and the new remainder 91, and apply the division lemma to get
1629 = 91 x 17 + 82
We consider the new divisor 91 and the new remainder 82,and apply the division lemma to get
91 = 82 x 1 + 9
We consider the new divisor 82 and the new remainder 9,and apply the division lemma to get
82 = 9 x 9 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 6789 and 1720 is 1
Notice that 1 = HCF(9,1) = HCF(82,9) = HCF(91,82) = HCF(1629,91) = HCF(1720,1629) = HCF(6789,1720) .
