HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 620, 223, 938 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 620, 223, 938 is 1 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, 223, 938 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, 223, 938 is 1.
HCF(620, 223, 938) = 1
HCF of 620, 223, 938 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, 223, 938 is 1.
Highest Common Factor of 620,223,938 is 1
Step 1: Since 620 > 223, we apply the division lemma to 620 and 223, to get
620 = 223 x 2 + 174
Step 2: Since the reminder 223 ≠ 0, we apply division lemma to 174 and 223, to get
223 = 174 x 1 + 49
Step 3: We consider the new divisor 174 and the new remainder 49, and apply the division lemma to get
174 = 49 x 3 + 27
We consider the new divisor 49 and the new remainder 27,and apply the division lemma to get
49 = 27 x 1 + 22
We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get
27 = 22 x 1 + 5
We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get
22 = 5 x 4 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 620 and 223 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(49,27) = HCF(174,49) = HCF(223,174) = HCF(620,223) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 938 > 1, we apply the division lemma to 938 and 1, to get
938 = 1 x 938 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 938 is 1
Notice that 1 = HCF(938,1) .
