HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 374, 640, 202 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 374, 640, 202 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 374, 640, 202 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 374, 640, 202 is 2.
HCF(374, 640, 202) = 2
HCF of 374, 640, 202 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 374, 640, 202 is 2.
Highest Common Factor of 374,640,202 is 2
Step 1: Since 640 > 374, we apply the division lemma to 640 and 374, to get
640 = 374 x 1 + 266
Step 2: Since the reminder 374 ≠ 0, we apply division lemma to 266 and 374, to get
374 = 266 x 1 + 108
Step 3: We consider the new divisor 266 and the new remainder 108, and apply the division lemma to get
266 = 108 x 2 + 50
We consider the new divisor 108 and the new remainder 50,and apply the division lemma to get
108 = 50 x 2 + 8
We consider the new divisor 50 and the new remainder 8,and apply the division lemma to get
50 = 8 x 6 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 374 and 640 is 2
Notice that 2 = HCF(8,2) = HCF(50,8) = HCF(108,50) = HCF(266,108) = HCF(374,266) = HCF(640,374) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 202 > 2, we apply the division lemma to 202 and 2, to get
202 = 2 x 101 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 202 is 2
Notice that 2 = HCF(202,2) .
