Given numbers are 724, 815, 91, 378
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(724, 815) = 590060
GCD(724, 815) = ( 724 x 815 ) / 590060
= 724 / 815
= 724
Step2:
LCM(1, 91) = 91
GCD(1, 91) = ( 1 x 91 ) / 91
= 1 / 91
= 1
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 724, 815, 91, 378 is 1
