HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 969, 609 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 969, 609 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 969, 609 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 969, 609 is 3.
HCF(969, 609) = 3
HCF of 969, 609 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 969, 609 is 3.
Highest Common Factor of 969,609 is 3
Step 1: Since 969 > 609, we apply the division lemma to 969 and 609, to get
969 = 609 x 1 + 360
Step 2: Since the reminder 609 ≠ 0, we apply division lemma to 360 and 609, to get
609 = 360 x 1 + 249
Step 3: We consider the new divisor 360 and the new remainder 249, and apply the division lemma to get
360 = 249 x 1 + 111
We consider the new divisor 249 and the new remainder 111,and apply the division lemma to get
249 = 111 x 2 + 27
We consider the new divisor 111 and the new remainder 27,and apply the division lemma to get
111 = 27 x 4 + 3
We consider the new divisor 27 and the new remainder 3,and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 969 and 609 is 3
Notice that 3 = HCF(27,3) = HCF(111,27) = HCF(249,111) = HCF(360,249) = HCF(609,360) = HCF(969,609) .
