HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 630, 925, 342 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 369, 630, 925, 342 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 369, 630, 925, 342 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 369, 630, 925, 342 is 1.
HCF(369, 630, 925, 342) = 1
HCF of 369, 630, 925, 342 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 369, 630, 925, 342 is 1.
Highest Common Factor of 369,630,925,342 is 1
Step 1: Since 630 > 369, we apply the division lemma to 630 and 369, to get
630 = 369 x 1 + 261
Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 261 and 369, to get
369 = 261 x 1 + 108
Step 3: We consider the new divisor 261 and the new remainder 108, and apply the division lemma to get
261 = 108 x 2 + 45
We consider the new divisor 108 and the new remainder 45,and apply the division lemma to get
108 = 45 x 2 + 18
We consider the new divisor 45 and the new remainder 18,and apply the division lemma to get
45 = 18 x 2 + 9
We consider the new divisor 18 and the new remainder 9,and apply the division lemma to get
18 = 9 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 369 and 630 is 9
Notice that 9 = HCF(18,9) = HCF(45,18) = HCF(108,45) = HCF(261,108) = HCF(369,261) = HCF(630,369) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 925 > 9, we apply the division lemma to 925 and 9, to get
925 = 9 x 102 + 7
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 7 and 9, to get
9 = 7 x 1 + 2
Step 3: We consider the new divisor 7 and the new remainder 2, and apply the division lemma to get
7 = 2 x 3 + 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 9 and 925 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(925,9) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 342 > 1, we apply the division lemma to 342 and 1, to get
342 = 1 x 342 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 342 is 1
Notice that 1 = HCF(342,1) .
