HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 70, 962, 494 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 70, 962, 494 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 70, 962, 494 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 70, 962, 494 is 2.
HCF(70, 962, 494) = 2
HCF of 70, 962, 494 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 70, 962, 494 is 2.
Highest Common Factor of 70,962,494 is 2
Step 1: Since 962 > 70, we apply the division lemma to 962 and 70, to get
962 = 70 x 13 + 52
Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 52 and 70, to get
70 = 52 x 1 + 18
Step 3: We consider the new divisor 52 and the new remainder 18, and apply the division lemma to get
52 = 18 x 2 + 16
We consider the new divisor 18 and the new remainder 16,and apply the division lemma to get
18 = 16 x 1 + 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 70 and 962 is 2
Notice that 2 = HCF(16,2) = HCF(18,16) = HCF(52,18) = HCF(70,52) = HCF(962,70) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 494 > 2, we apply the division lemma to 494 and 2, to get
494 = 2 x 247 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 494 is 2
Notice that 2 = HCF(494,2) .
