HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7077, 654 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 7077, 654 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 7077, 654 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 7077, 654 is 3.
HCF(7077, 654) = 3
HCF of 7077, 654 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 7077, 654 is 3.
Highest Common Factor of 7077,654 is 3
Step 1: Since 7077 > 654, we apply the division lemma to 7077 and 654, to get
7077 = 654 x 10 + 537
Step 2: Since the reminder 654 ≠ 0, we apply division lemma to 537 and 654, to get
654 = 537 x 1 + 117
Step 3: We consider the new divisor 537 and the new remainder 117, and apply the division lemma to get
537 = 117 x 4 + 69
We consider the new divisor 117 and the new remainder 69,and apply the division lemma to get
117 = 69 x 1 + 48
We consider the new divisor 69 and the new remainder 48,and apply the division lemma to get
69 = 48 x 1 + 21
We consider the new divisor 48 and the new remainder 21,and apply the division lemma to get
48 = 21 x 2 + 6
We consider the new divisor 21 and the new remainder 6,and apply the division lemma to get
21 = 6 x 3 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 7077 and 654 is 3
Notice that 3 = HCF(6,3) = HCF(21,6) = HCF(48,21) = HCF(69,48) = HCF(117,69) = HCF(537,117) = HCF(654,537) = HCF(7077,654) .
