HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 455, 2933 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 455, 2933 is 7 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 455, 2933 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 455, 2933 is 7.
HCF(455, 2933) = 7
HCF of 455, 2933 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 455, 2933 is 7.
Highest Common Factor of 455,2933 is 7
Step 1: Since 2933 > 455, we apply the division lemma to 2933 and 455, to get
2933 = 455 x 6 + 203
Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 203 and 455, to get
455 = 203 x 2 + 49
Step 3: We consider the new divisor 203 and the new remainder 49, and apply the division lemma to get
203 = 49 x 4 + 7
We consider the new divisor 49 and the new remainder 7, and apply the division lemma to get
49 = 7 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 455 and 2933 is 7
Notice that 7 = HCF(49,7) = HCF(203,49) = HCF(455,203) = HCF(2933,455) .
