HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 507, 620 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 380, 507, 620 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 380, 507, 620 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 380, 507, 620 is 1.
HCF(380, 507, 620) = 1
HCF of 380, 507, 620 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 380, 507, 620 is 1.
Highest Common Factor of 380,507,620 is 1
Step 1: Since 507 > 380, we apply the division lemma to 507 and 380, to get
507 = 380 x 1 + 127
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 127 and 380, to get
380 = 127 x 2 + 126
Step 3: We consider the new divisor 127 and the new remainder 126, and apply the division lemma to get
127 = 126 x 1 + 1
We consider the new divisor 126 and the new remainder 1, and apply the division lemma to get
126 = 1 x 126 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 380 and 507 is 1
Notice that 1 = HCF(126,1) = HCF(127,126) = HCF(380,127) = HCF(507,380) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 620 > 1, we apply the division lemma to 620 and 1, to get
620 = 1 x 620 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 620 is 1
Notice that 1 = HCF(620,1) .
