HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 1677, 1245 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 1677, 1245 is 3 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 1677, 1245 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 1677, 1245 is 3.
HCF(1677, 1245) = 3
HCF of 1677, 1245 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 1677, 1245 is 3.
Highest Common Factor of 1677,1245 is 3
Step 1: Since 1677 > 1245, we apply the division lemma to 1677 and 1245, to get
1677 = 1245 x 1 + 432
Step 2: Since the reminder 1245 ≠ 0, we apply division lemma to 432 and 1245, to get
1245 = 432 x 2 + 381
Step 3: We consider the new divisor 432 and the new remainder 381, and apply the division lemma to get
432 = 381 x 1 + 51
We consider the new divisor 381 and the new remainder 51,and apply the division lemma to get
381 = 51 x 7 + 24
We consider the new divisor 51 and the new remainder 24,and apply the division lemma to get
51 = 24 x 2 + 3
We consider the new divisor 24 and the new remainder 3,and apply the division lemma to get
24 = 3 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 1677 and 1245 is 3
Notice that 3 = HCF(24,3) = HCF(51,24) = HCF(381,51) = HCF(432,381) = HCF(1245,432) = HCF(1677,1245) .
