Given numbers are 975, 420, 111, 916
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(975, 420) = 27300
GCD(975, 420) = ( 975 x 420 ) / 27300
= 975 / 420
= 975
Step2:
LCM(15, 111) = 555
GCD(15, 111) = ( 15 x 111 ) / 555
= 15 / 111
= 15
Step3:
LCM(3, 916) = 2748
GCD(3, 916) = ( 3 x 916 ) / 2748
= 3 / 916
= 3
So, Greatest Common Divisor of 975, 420, 111, 916 is 1
