Given numbers are 172, 215, 776, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(172, 215) = 860
GCD(172, 215) = ( 172 x 215 ) / 860
= 172 / 215
= 172
Step2:
LCM(43, 776) = 33368
GCD(43, 776) = ( 43 x 776 ) / 33368
= 43 / 776
= 43
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 172, 215, 776, 815 is 1
