HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 207, 702 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 207, 702 is 9 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 207, 702 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 207, 702 is 9.
HCF(207, 702) = 9
HCF of 207, 702 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 207, 702 is 9.
Highest Common Factor of 207,702 is 9
Step 1: Since 702 > 207, we apply the division lemma to 702 and 207, to get
702 = 207 x 3 + 81
Step 2: Since the reminder 207 ≠ 0, we apply division lemma to 81 and 207, to get
207 = 81 x 2 + 45
Step 3: We consider the new divisor 81 and the new remainder 45, and apply the division lemma to get
81 = 45 x 1 + 36
We consider the new divisor 45 and the new remainder 36,and apply the division lemma to get
45 = 36 x 1 + 9
We consider the new divisor 36 and the new remainder 9,and apply the division lemma to get
36 = 9 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 207 and 702 is 9
Notice that 9 = HCF(36,9) = HCF(45,36) = HCF(81,45) = HCF(207,81) = HCF(702,207) .
