HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 862, 780 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 862, 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 862, 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 862, 780 is 2.
HCF(862, 780) = 2
HCF of 862, 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 862, 780 is 2.
Highest Common Factor of 862,780 is 2
Step 1: Since 862 > 780, we apply the division lemma to 862 and 780, to get
862 = 780 x 1 + 82
Step 2: Since the reminder 780 ≠ 0, we apply division lemma to 82 and 780, to get
780 = 82 x 9 + 42
Step 3: We consider the new divisor 82 and the new remainder 42, and apply the division lemma to get
82 = 42 x 1 + 40
We consider the new divisor 42 and the new remainder 40,and apply the division lemma to get
42 = 40 x 1 + 2
We consider the new divisor 40 and the new remainder 2,and apply the division lemma to get
40 = 2 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 862 and 780 is 2
Notice that 2 = HCF(40,2) = HCF(42,40) = HCF(82,42) = HCF(780,82) = HCF(862,780) .
