Given numbers are 780, 987, 379, 975
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 987) = 256620
GCD(780, 987) = ( 780 x 987 ) / 256620
= 780 / 987
= 780
Step2:
LCM(3, 379) = 1137
GCD(3, 379) = ( 3 x 379 ) / 1137
= 3 / 379
= 3
Step3:
LCM(1, 975) = 975
GCD(1, 975) = ( 1 x 975 ) / 975
= 1 / 975
= 1
So, Greatest Common Divisor of 780, 987, 379, 975 is 1
