Given numbers are 974, 685, 142, 215
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(974, 685) = 667190
GCD(974, 685) = ( 974 x 685 ) / 667190
= 974 / 685
= 974
Step2:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
Step3:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
So, Greatest Common Divisor of 974, 685, 142, 215 is 1
