HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 672, 245 i.e. 7 the largest integer that leaves a remainder zero for all numbers.
HCF of 672, 245 is 7 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 672, 245 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 672, 245 is 7.
HCF(672, 245) = 7
HCF of 672, 245 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 672, 245 is 7.
Highest Common Factor of 672,245 is 7
Step 1: Since 672 > 245, we apply the division lemma to 672 and 245, to get
672 = 245 x 2 + 182
Step 2: Since the reminder 245 ≠ 0, we apply division lemma to 182 and 245, to get
245 = 182 x 1 + 63
Step 3: We consider the new divisor 182 and the new remainder 63, and apply the division lemma to get
182 = 63 x 2 + 56
We consider the new divisor 63 and the new remainder 56,and apply the division lemma to get
63 = 56 x 1 + 7
We consider the new divisor 56 and the new remainder 7,and apply the division lemma to get
56 = 7 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 672 and 245 is 7
Notice that 7 = HCF(56,7) = HCF(63,56) = HCF(182,63) = HCF(245,182) = HCF(672,245) .
