HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 690, 322, 436 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 690, 322, 436 is 2 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 690, 322, 436 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 690, 322, 436 is 2.
HCF(690, 322, 436) = 2
HCF of 690, 322, 436 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 690, 322, 436 is 2.
Highest Common Factor of 690,322,436 is 2
Step 1: Since 690 > 322, we apply the division lemma to 690 and 322, to get
690 = 322 x 2 + 46
Step 2: Since the reminder 322 ≠ 0, we apply division lemma to 46 and 322, to get
322 = 46 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 46, the HCF of 690 and 322 is 46
Notice that 46 = HCF(322,46) = HCF(690,322) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 436 > 46, we apply the division lemma to 436 and 46, to get
436 = 46 x 9 + 22
Step 2: Since the reminder 46 ≠ 0, we apply division lemma to 22 and 46, to get
46 = 22 x 2 + 2
Step 3: We consider the new divisor 22 and the new remainder 2, and apply the division lemma to get
22 = 2 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 46 and 436 is 2
Notice that 2 = HCF(22,2) = HCF(46,22) = HCF(436,46) .
