Given numbers are 415, 780, 881, 357
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 780) = 64740
GCD(415, 780) = ( 415 x 780 ) / 64740
= 415 / 780
= 415
Step2:
LCM(5, 881) = 4405
GCD(5, 881) = ( 5 x 881 ) / 4405
= 5 / 881
= 5
Step3:
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
= 1 / 357
= 1
So, Greatest Common Divisor of 415, 780, 881, 357 is 1
