HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 9921, 1655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 9921, 1655 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 9921, 1655 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 9921, 1655 is 1.
HCF(9921, 1655) = 1
HCF of 9921, 1655 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 9921, 1655 is 1.
Highest Common Factor of 9921,1655 is 1
Step 1: Since 9921 > 1655, we apply the division lemma to 9921 and 1655, to get
9921 = 1655 x 5 + 1646
Step 2: Since the reminder 1655 ≠ 0, we apply division lemma to 1646 and 1655, to get
1655 = 1646 x 1 + 9
Step 3: We consider the new divisor 1646 and the new remainder 9, and apply the division lemma to get
1646 = 9 x 182 + 8
We consider the new divisor 9 and the new remainder 8,and apply the division lemma to get
9 = 8 x 1 + 1
We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get
8 = 1 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 9921 and 1655 is 1
Notice that 1 = HCF(8,1) = HCF(9,8) = HCF(1646,9) = HCF(1655,1646) = HCF(9921,1655) .
