HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 273, 639 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 273, 639 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 273, 639 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 273, 639 is 3.
HCF(273, 639) = 3
HCF of 273, 639 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 273, 639 is 3.
Highest Common Factor of 273,639 is 3
Step 1: Since 639 > 273, we apply the division lemma to 639 and 273, to get
639 = 273 x 2 + 93
Step 2: Since the reminder 273 ≠ 0, we apply division lemma to 93 and 273, to get
273 = 93 x 2 + 87
Step 3: We consider the new divisor 93 and the new remainder 87, and apply the division lemma to get
93 = 87 x 1 + 6
We consider the new divisor 87 and the new remainder 6,and apply the division lemma to get
87 = 6 x 14 + 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 273 and 639 is 3
Notice that 3 = HCF(6,3) = HCF(87,6) = HCF(93,87) = HCF(273,93) = HCF(639,273) .
