HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1664, 9820 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 1664, 9820 is 4 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 1664, 9820 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 1664, 9820 is 4.
HCF(1664, 9820) = 4
HCF of 1664, 9820 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1664, 9820 is 4.
Highest Common Factor of 1664,9820 is 4
Step 1: Since 9820 > 1664, we apply the division lemma to 9820 and 1664, to get
9820 = 1664 x 5 + 1500
Step 2: Since the reminder 1664 ≠ 0, we apply division lemma to 1500 and 1664, to get
1664 = 1500 x 1 + 164
Step 3: We consider the new divisor 1500 and the new remainder 164, and apply the division lemma to get
1500 = 164 x 9 + 24
We consider the new divisor 164 and the new remainder 24,and apply the division lemma to get
164 = 24 x 6 + 20
We consider the new divisor 24 and the new remainder 20,and apply the division lemma to get
24 = 20 x 1 + 4
We consider the new divisor 20 and the new remainder 4,and apply the division lemma to get
20 = 4 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 1664 and 9820 is 4
Notice that 4 = HCF(20,4) = HCF(24,20) = HCF(164,24) = HCF(1500,164) = HCF(1664,1500) = HCF(9820,1664) .
