Given numbers are 771, 792, 757, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(771, 792) = 203544
GCD(771, 792) = ( 771 x 792 ) / 203544
= 771 / 792
= 771
Step2:
LCM(3, 757) = 2271
GCD(3, 757) = ( 3 x 757 ) / 2271
= 3 / 757
= 3
Step3:
LCM(1, 245) = 245
GCD(1, 245) = ( 1 x 245 ) / 245
= 1 / 245
= 1
So, Greatest Common Divisor of 771, 792, 757, 245 is 1
