HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 70647 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 70647 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 789, 70647 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 789, 70647 is 3.
HCF(789, 70647) = 3
HCF of 789, 70647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 789, 70647 is 3.
Highest Common Factor of 789,70647 is 3
Step 1: Since 70647 > 789, we apply the division lemma to 70647 and 789, to get
70647 = 789 x 89 + 426
Step 2: Since the reminder 789 ≠ 0, we apply division lemma to 426 and 789, to get
789 = 426 x 1 + 363
Step 3: We consider the new divisor 426 and the new remainder 363, and apply the division lemma to get
426 = 363 x 1 + 63
We consider the new divisor 363 and the new remainder 63,and apply the division lemma to get
363 = 63 x 5 + 48
We consider the new divisor 63 and the new remainder 48,and apply the division lemma to get
63 = 48 x 1 + 15
We consider the new divisor 48 and the new remainder 15,and apply the division lemma to get
48 = 15 x 3 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 789 and 70647 is 3
Notice that 3 = HCF(15,3) = HCF(48,15) = HCF(63,48) = HCF(363,63) = HCF(426,363) = HCF(789,426) = HCF(70647,789) .
