GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(395, 890) = 70310
GCD(395, 890) = ( 395 x 890 ) / 70310
= 395 / 890
= 395
Step2:
LCM(5, 618) = 3090
GCD(5, 618) = ( 5 x 618 ) / 3090
= 5 / 618
= 5
Step3:
LCM(1, 972) = 972
GCD(1, 972) = ( 1 x 972 ) / 972
= 1 / 972
= 1
So, Greatest Common Divisor of 395, 890, 618, 972 is 1
