HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 364, 621 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 364, 621 is 1 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 364, 621 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 364, 621 is 1.
HCF(364, 621) = 1
HCF of 364, 621 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 364, 621 is 1.
Highest Common Factor of 364,621 is 1
Step 1: Since 621 > 364, we apply the division lemma to 621 and 364, to get
621 = 364 x 1 + 257
Step 2: Since the reminder 364 ≠ 0, we apply division lemma to 257 and 364, to get
364 = 257 x 1 + 107
Step 3: We consider the new divisor 257 and the new remainder 107, and apply the division lemma to get
257 = 107 x 2 + 43
We consider the new divisor 107 and the new remainder 43,and apply the division lemma to get
107 = 43 x 2 + 21
We consider the new divisor 43 and the new remainder 21,and apply the division lemma to get
43 = 21 x 2 + 1
We consider the new divisor 21 and the new remainder 1,and apply the division lemma to get
21 = 1 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 364 and 621 is 1
Notice that 1 = HCF(21,1) = HCF(43,21) = HCF(107,43) = HCF(257,107) = HCF(364,257) = HCF(621,364) .
