GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(578, 520) = 150280
GCD(578, 520) = ( 578 x 520 ) / 150280
= 578 / 520
= 578
Step2:
LCM(2, 836) = 836
GCD(2, 836) = ( 2 x 836 ) / 836
= 2 / 836
= 2
Step3:
LCM(2, 830) = 830
GCD(2, 830) = ( 2 x 830 ) / 830
= 2 / 830
= 2
So, Greatest Common Divisor of 578, 520, 836, 830 is 2
