HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 370, 925, 420 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 370, 925, 420 is 5 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 370, 925, 420 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 370, 925, 420 is 5.
HCF(370, 925, 420) = 5
HCF of 370, 925, 420 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 370, 925, 420 is 5.
Highest Common Factor of 370,925,420 is 5
Step 1: Since 925 > 370, we apply the division lemma to 925 and 370, to get
925 = 370 x 2 + 185
Step 2: Since the reminder 370 ≠ 0, we apply division lemma to 185 and 370, to get
370 = 185 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 185, the HCF of 370 and 925 is 185
Notice that 185 = HCF(370,185) = HCF(925,370) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 420 > 185, we apply the division lemma to 420 and 185, to get
420 = 185 x 2 + 50
Step 2: Since the reminder 185 ≠ 0, we apply division lemma to 50 and 185, to get
185 = 50 x 3 + 35
Step 3: We consider the new divisor 50 and the new remainder 35, and apply the division lemma to get
50 = 35 x 1 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 185 and 420 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(50,35) = HCF(185,50) = HCF(420,185) .
