GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 398) = 155618
GCD(782, 398) = ( 782 x 398 ) / 155618
= 782 / 398
= 782
Step2:
LCM(2, 495) = 990
GCD(2, 495) = ( 2 x 495 ) / 990
= 2 / 495
= 2
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 782, 398, 495, 755 is 1
