HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 938, 496 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 938, 496 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 620, 938, 496 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 620, 938, 496 is 2.
HCF(620, 938, 496) = 2
HCF of 620, 938, 496 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 620, 938, 496 is 2.
Highest Common Factor of 620,938,496 is 2
Step 1: Since 938 > 620, we apply the division lemma to 938 and 620, to get
938 = 620 x 1 + 318
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 318 and 620, to get
620 = 318 x 1 + 302
Step 3: We consider the new divisor 318 and the new remainder 302, and apply the division lemma to get
318 = 302 x 1 + 16
We consider the new divisor 302 and the new remainder 16,and apply the division lemma to get
302 = 16 x 18 + 14
We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get
16 = 14 x 1 + 2
We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get
14 = 2 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 620 and 938 is 2
Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(302,16) = HCF(318,302) = HCF(620,318) = HCF(938,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 496 > 2, we apply the division lemma to 496 and 2, to get
496 = 2 x 248 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 496 is 2
Notice that 2 = HCF(496,2) .
