HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 695, 77393 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 695, 77393 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 695, 77393 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 695, 77393 is 1.
HCF(695, 77393) = 1
HCF of 695, 77393 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 695, 77393 is 1.
Highest Common Factor of 695,77393 is 1
Step 1: Since 77393 > 695, we apply the division lemma to 77393 and 695, to get
77393 = 695 x 111 + 248
Step 2: Since the reminder 695 ≠ 0, we apply division lemma to 248 and 695, to get
695 = 248 x 2 + 199
Step 3: We consider the new divisor 248 and the new remainder 199, and apply the division lemma to get
248 = 199 x 1 + 49
We consider the new divisor 199 and the new remainder 49,and apply the division lemma to get
199 = 49 x 4 + 3
We consider the new divisor 49 and the new remainder 3,and apply the division lemma to get
49 = 3 x 16 + 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 695 and 77393 is 1
Notice that 1 = HCF(3,1) = HCF(49,3) = HCF(199,49) = HCF(248,199) = HCF(695,248) = HCF(77393,695) .
