HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 820, 573, 377 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 820, 573, 377 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 820, 573, 377 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 820, 573, 377 is 1.
HCF(820, 573, 377) = 1
HCF of 820, 573, 377 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 820, 573, 377 is 1.
Highest Common Factor of 820,573,377 is 1
Step 1: Since 820 > 573, we apply the division lemma to 820 and 573, to get
820 = 573 x 1 + 247
Step 2: Since the reminder 573 ≠ 0, we apply division lemma to 247 and 573, to get
573 = 247 x 2 + 79
Step 3: We consider the new divisor 247 and the new remainder 79, and apply the division lemma to get
247 = 79 x 3 + 10
We consider the new divisor 79 and the new remainder 10,and apply the division lemma to get
79 = 10 x 7 + 9
We consider the new divisor 10 and the new remainder 9,and apply the division lemma to get
10 = 9 x 1 + 1
We consider the new divisor 9 and the new remainder 1,and apply the division lemma to get
9 = 1 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 820 and 573 is 1
Notice that 1 = HCF(9,1) = HCF(10,9) = HCF(79,10) = HCF(247,79) = HCF(573,247) = HCF(820,573) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 377 > 1, we apply the division lemma to 377 and 1, to get
377 = 1 x 377 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 377 is 1
Notice that 1 = HCF(377,1) .
