HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 667, 78860 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 667, 78860 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 667, 78860 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 667, 78860 is 1.
HCF(667, 78860) = 1
HCF of 667, 78860 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 667, 78860 is 1.
Highest Common Factor of 667,78860 is 1
Step 1: Since 78860 > 667, we apply the division lemma to 78860 and 667, to get
78860 = 667 x 118 + 154
Step 2: Since the reminder 667 ≠ 0, we apply division lemma to 154 and 667, to get
667 = 154 x 4 + 51
Step 3: We consider the new divisor 154 and the new remainder 51, and apply the division lemma to get
154 = 51 x 3 + 1
We consider the new divisor 51 and the new remainder 1, and apply the division lemma to get
51 = 1 x 51 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 667 and 78860 is 1
Notice that 1 = HCF(51,1) = HCF(154,51) = HCF(667,154) = HCF(78860,667) .
