Given numbers are 782, 441, 151, 285
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 441) = 344862
GCD(782, 441) = ( 782 x 441 ) / 344862
= 782 / 441
= 782
Step2:
LCM(1, 151) = 151
GCD(1, 151) = ( 1 x 151 ) / 151
= 1 / 151
= 1
Step3:
LCM(1, 285) = 285
GCD(1, 285) = ( 1 x 285 ) / 285
= 1 / 285
= 1
So, Greatest Common Divisor of 782, 441, 151, 285 is 1
