HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 946, 780 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 946, 780 is 2 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 946, 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 946, 780 is 2.
HCF(946, 780) = 2
HCF of 946, 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 946, 780 is 2.
Highest Common Factor of 946,780 is 2
Step 1: Since 946 > 780, we apply the division lemma to 946 and 780, to get
946 = 780 x 1 + 166
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 166 and 780, to get
780 = 166 x 4 + 116
Step 3: We consider the new divisor 166 and the new remainder 116, and apply the division lemma to get
166 = 116 x 1 + 50
We consider the new divisor 116 and the new remainder 50,and apply the division lemma to get
116 = 50 x 2 + 16
We consider the new divisor 50 and the new remainder 16,and apply the division lemma to get
50 = 16 x 3 + 2
We consider the new divisor 16 and the new remainder 2,and apply the division lemma to get
16 = 2 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 946 and 780 is 2
Notice that 2 = HCF(16,2) = HCF(50,16) = HCF(116,50) = HCF(166,116) = HCF(780,166) = HCF(946,780) .
