GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(452, 644) = 72772
GCD(452, 644) = ( 452 x 644 ) / 72772
= 452 / 644
= 452
Step2:
LCM(4, 588) = 588
GCD(4, 588) = ( 4 x 588 ) / 588
= 4 / 588
= 4
Step3:
LCM(4, 438) = 876
GCD(4, 438) = ( 4 x 438 ) / 876
= 4 / 438
= 4
So, Greatest Common Divisor of 452, 644, 588, 438 is 2
