GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(380, 888) = 84360
GCD(380, 888) = ( 380 x 888 ) / 84360
= 380 / 888
= 380
Step2:
LCM(4, 220) = 220
GCD(4, 220) = ( 4 x 220 ) / 220
= 4 / 220
= 4
Step3:
LCM(4, 987) = 3948
GCD(4, 987) = ( 4 x 987 ) / 3948
= 4 / 987
= 4
So, Greatest Common Divisor of 380, 888, 220, 987 is 1
