HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 522, 342 i.e. 9 the largest integer that leaves a remainder zero for all numbers.
HCF of 369, 522, 342 is 9 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, 522, 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, 522, 342 is 9.
HCF(369, 522, 342) = 9
HCF of 369, 522, 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, 522, 342 is 9.
Highest Common Factor of 369,522,342 is 9
Step 1: Since 522 > 369, we apply the division lemma to 522 and 369, to get
522 = 369 x 1 + 153
Step 2: Since the reminder 369 ≠ 0, we apply division lemma to 153 and 369, to get
369 = 153 x 2 + 63
Step 3: We consider the new divisor 153 and the new remainder 63, and apply the division lemma to get
153 = 63 x 2 + 27
We consider the new divisor 63 and the new remainder 27,and apply the division lemma to get
63 = 27 x 2 + 9
We consider the new divisor 27 and the new remainder 9,and apply the division lemma to get
27 = 9 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 369 and 522 is 9
Notice that 9 = HCF(27,9) = HCF(63,27) = HCF(153,63) = HCF(369,153) = HCF(522,369) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 342 > 9, we apply the division lemma to 342 and 9, to get
342 = 9 x 38 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 9 and 342 is 9
Notice that 9 = HCF(342,9) .
