GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(802, 980) = 392980
GCD(802, 980) = ( 802 x 980 ) / 392980
= 802 / 980
= 802
Step2:
LCM(2, 102) = 102
GCD(2, 102) = ( 2 x 102 ) / 102
= 2 / 102
= 2
Step3:
LCM(2, 392) = 392
GCD(2, 392) = ( 2 x 392 ) / 392
= 2 / 392
= 2
So, Greatest Common Divisor of 802, 980, 102, 392 is 2
