Given numbers are 780, 375, 277, 520
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 375) = 19500
GCD(780, 375) = ( 780 x 375 ) / 19500
= 780 / 375
= 780
Step2:
LCM(15, 277) = 4155
GCD(15, 277) = ( 15 x 277 ) / 4155
= 15 / 277
= 15
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 780, 375, 277, 520 is 1
