Given numbers are 252, 956, 543, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(252, 956) = 60228
GCD(252, 956) = ( 252 x 956 ) / 60228
= 252 / 956
= 252
Step2:
LCM(4, 543) = 2172
GCD(4, 543) = ( 4 x 543 ) / 2172
= 4 / 543
= 4
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 252, 956, 543, 420 is 1
