Given numbers are 978, 661, 931, 377
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(978, 661) = 646458
GCD(978, 661) = ( 978 x 661 ) / 646458
= 978 / 661
= 978
Step2:
LCM(1, 931) = 931
GCD(1, 931) = ( 1 x 931 ) / 931
= 1 / 931
= 1
Step3:
LCM(1, 377) = 377
GCD(1, 377) = ( 1 x 377 ) / 377
= 1 / 377
= 1
So, Greatest Common Divisor of 978, 661, 931, 377 is 1
