Given numbers are 715, 278, 69, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(715, 278) = 198770
GCD(715, 278) = ( 715 x 278 ) / 198770
= 715 / 278
= 715
Step2:
LCM(1, 69) = 69
GCD(1, 69) = ( 1 x 69 ) / 69
= 1 / 69
= 1
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 715, 278, 69, 193 is 1
