GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(804, 532) = 106932
GCD(804, 532) = ( 804 x 532 ) / 106932
= 804 / 532
= 804
Step2:
LCM(4, 440) = 440
GCD(4, 440) = ( 4 x 440 ) / 440
= 4 / 440
= 4
Step3:
LCM(4, 978) = 1956
GCD(4, 978) = ( 4 x 978 ) / 1956
= 4 / 978
= 4
So, Greatest Common Divisor of 804, 532, 440, 978 is 2
