Given numbers are 658, 638, 867, 543
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 638) = 209902
GCD(658, 638) = ( 658 x 638 ) / 209902
= 658 / 638
= 658
Step2:
LCM(2, 867) = 1734
GCD(2, 867) = ( 2 x 867 ) / 1734
= 2 / 867
= 2
Step3:
LCM(1, 543) = 543
GCD(1, 543) = ( 1 x 543 ) / 543
= 1 / 543
= 1
So, Greatest Common Divisor of 658, 638, 867, 543 is 1
