HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 379, 427, 19, 660 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 379, 427, 19, 660 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 379, 427, 19, 660 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 379, 427, 19, 660 is 1.
HCF(379, 427, 19, 660) = 1
HCF of 379, 427, 19, 660 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 379, 427, 19, 660 is 1.
Highest Common Factor of 379,427,19,660 is 1
Step 1: Since 427 > 379, we apply the division lemma to 427 and 379, to get
427 = 379 x 1 + 48
Step 2: Since the reminder 379 ≠ 0, we apply division lemma to 48 and 379, to get
379 = 48 x 7 + 43
Step 3: We consider the new divisor 48 and the new remainder 43, and apply the division lemma to get
48 = 43 x 1 + 5
We consider the new divisor 43 and the new remainder 5,and apply the division lemma to get
43 = 5 x 8 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 379 and 427 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(43,5) = HCF(48,43) = HCF(379,48) = HCF(427,379) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 19 > 1, we apply the division lemma to 19 and 1, to get
19 = 1 x 19 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 19 is 1
Notice that 1 = HCF(19,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 660 > 1, we apply the division lemma to 660 and 1, to get
660 = 1 x 660 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 660 is 1
Notice that 1 = HCF(660,1) .
