GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 756) = 590436
GCD(781, 756) = ( 781 x 756 ) / 590436
= 781 / 756
= 781
Step2:
LCM(1, 505) = 505
GCD(1, 505) = ( 1 x 505 ) / 505
= 1 / 505
= 1
Step3:
LCM(1, 832) = 832
GCD(1, 832) = ( 1 x 832 ) / 832
= 1 / 832
= 1
So, Greatest Common Divisor of 781, 756, 505, 832 is 1
