HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7623, 7989 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 7623, 7989 is 3 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 7623, 7989 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 7623, 7989 is 3.
HCF(7623, 7989) = 3
HCF of 7623, 7989 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7623, 7989 is 3.
Highest Common Factor of 7623,7989 is 3
Step 1: Since 7989 > 7623, we apply the division lemma to 7989 and 7623, to get
7989 = 7623 x 1 + 366
Step 2: Since the reminder 7623 ≠ 0, we apply division lemma to 366 and 7623, to get
7623 = 366 x 20 + 303
Step 3: We consider the new divisor 366 and the new remainder 303, and apply the division lemma to get
366 = 303 x 1 + 63
We consider the new divisor 303 and the new remainder 63,and apply the division lemma to get
303 = 63 x 4 + 51
We consider the new divisor 63 and the new remainder 51,and apply the division lemma to get
63 = 51 x 1 + 12
We consider the new divisor 51 and the new remainder 12,and apply the division lemma to get
51 = 12 x 4 + 3
We consider the new divisor 12 and the new remainder 3,and apply the division lemma to get
12 = 3 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 7623 and 7989 is 3
Notice that 3 = HCF(12,3) = HCF(51,12) = HCF(63,51) = HCF(303,63) = HCF(366,303) = HCF(7623,366) = HCF(7989,7623) .
