HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 290, 654 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 290, 654 is 2 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 290, 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 290, 654 is 2.
HCF(290, 654) = 2
HCF of 290, 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 290, 654 is 2.
Highest Common Factor of 290,654 is 2
Step 1: Since 654 > 290, we apply the division lemma to 654 and 290, to get
654 = 290 x 2 + 74
Step 2: Since the reminder 290 ≠ 0, we apply division lemma to 74 and 290, to get
290 = 74 x 3 + 68
Step 3: We consider the new divisor 74 and the new remainder 68, and apply the division lemma to get
74 = 68 x 1 + 6
We consider the new divisor 68 and the new remainder 6,and apply the division lemma to get
68 = 6 x 11 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 290 and 654 is 2
Notice that 2 = HCF(6,2) = HCF(68,6) = HCF(74,68) = HCF(290,74) = HCF(654,290) .
