HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 962, 420 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 962, 420 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 962, 420 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 962, 420 is 2.
HCF(962, 420) = 2
HCF of 962, 420 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 962, 420 is 2.
Highest Common Factor of 962,420 is 2
Step 1: Since 962 > 420, we apply the division lemma to 962 and 420, to get
962 = 420 x 2 + 122
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 122 and 420, to get
420 = 122 x 3 + 54
Step 3: We consider the new divisor 122 and the new remainder 54, and apply the division lemma to get
122 = 54 x 2 + 14
We consider the new divisor 54 and the new remainder 14,and apply the division lemma to get
54 = 14 x 3 + 12
We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get
14 = 12 x 1 + 2
We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get
12 = 2 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 962 and 420 is 2
Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(54,14) = HCF(122,54) = HCF(420,122) = HCF(962,420) .
