Given numbers are 374, 780, 644, 375
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(374, 780) = 145860
GCD(374, 780) = ( 374 x 780 ) / 145860
= 374 / 780
= 374
Step2:
LCM(2, 644) = 644
GCD(2, 644) = ( 2 x 644 ) / 644
= 2 / 644
= 2
Step3:
LCM(2, 375) = 750
GCD(2, 375) = ( 2 x 375 ) / 750
= 2 / 375
= 2
So, Greatest Common Divisor of 374, 780, 644, 375 is 1
