HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 984, 780 i.e. 12 the largest integer that leaves a remainder zero for all numbers.
HCF of 984, 780 is 12 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 984, 780 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 984, 780 is 12.
HCF(984, 780) = 12
HCF of 984, 780 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 984, 780 is 12.
Highest Common Factor of 984,780 is 12
Step 1: Since 984 > 780, we apply the division lemma to 984 and 780, to get
984 = 780 x 1 + 204
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 204 and 780, to get
780 = 204 x 3 + 168
Step 3: We consider the new divisor 204 and the new remainder 168, and apply the division lemma to get
204 = 168 x 1 + 36
We consider the new divisor 168 and the new remainder 36,and apply the division lemma to get
168 = 36 x 4 + 24
We consider the new divisor 36 and the new remainder 24,and apply the division lemma to get
36 = 24 x 1 + 12
We consider the new divisor 24 and the new remainder 12,and apply the division lemma to get
24 = 12 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 984 and 780 is 12
Notice that 12 = HCF(24,12) = HCF(36,24) = HCF(168,36) = HCF(204,168) = HCF(780,204) = HCF(984,780) .
