HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 697, 190 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 697, 190 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 697, 190 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 697, 190 is 1.
HCF(697, 190) = 1
HCF of 697, 190 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 697, 190 is 1.
Highest Common Factor of 697,190 is 1
Step 1: Since 697 > 190, we apply the division lemma to 697 and 190, to get
697 = 190 x 3 + 127
Step 2: Since the reminder 190 ≠ 0, we apply division lemma to 127 and 190, to get
190 = 127 x 1 + 63
Step 3: We consider the new divisor 127 and the new remainder 63, and apply the division lemma to get
127 = 63 x 2 + 1
We consider the new divisor 63 and the new remainder 1, and apply the division lemma to get
63 = 1 x 63 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 697 and 190 is 1
Notice that 1 = HCF(63,1) = HCF(127,63) = HCF(190,127) = HCF(697,190) .
