Given numbers are 660, 980, 842, 252
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 980) = 32340
GCD(660, 980) = ( 660 x 980 ) / 32340
= 660 / 980
= 660
Step2:
LCM(20, 842) = 8420
GCD(20, 842) = ( 20 x 842 ) / 8420
= 20 / 842
= 20
Step3:
LCM(2, 252) = 252
GCD(2, 252) = ( 2 x 252 ) / 252
= 2 / 252
= 2
So, Greatest Common Divisor of 660, 980, 842, 252 is 2
