Given numbers are 969, 975, 642, 380
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(969, 975) = 314925
GCD(969, 975) = ( 969 x 975 ) / 314925
= 969 / 975
= 969
Step2:
LCM(3, 642) = 642
GCD(3, 642) = ( 3 x 642 ) / 642
= 3 / 642
= 3
Step3:
LCM(3, 380) = 1140
GCD(3, 380) = ( 3 x 380 ) / 1140
= 3 / 380
= 3
So, Greatest Common Divisor of 969, 975, 642, 380 is 1
