HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 662, 545 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 662, 545 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 662, 545 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 662, 545 is 1.
HCF(662, 545) = 1
HCF of 662, 545 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 662, 545 is 1.
Highest Common Factor of 662,545 is 1
Step 1: Since 662 > 545, we apply the division lemma to 662 and 545, to get
662 = 545 x 1 + 117
Step 2: Since the reminder 545 ≠ 0, we apply division lemma to 117 and 545, to get
545 = 117 x 4 + 77
Step 3: We consider the new divisor 117 and the new remainder 77, and apply the division lemma to get
117 = 77 x 1 + 40
We consider the new divisor 77 and the new remainder 40,and apply the division lemma to get
77 = 40 x 1 + 37
We consider the new divisor 40 and the new remainder 37,and apply the division lemma to get
40 = 37 x 1 + 3
We consider the new divisor 37 and the new remainder 3,and apply the division lemma to get
37 = 3 x 12 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 662 and 545 is 1
Notice that 1 = HCF(3,1) = HCF(37,3) = HCF(40,37) = HCF(77,40) = HCF(117,77) = HCF(545,117) = HCF(662,545) .
