Given numbers are 685, 735, 321, 947
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(685, 735) = 100695
GCD(685, 735) = ( 685 x 735 ) / 100695
= 685 / 735
= 685
Step2:
LCM(5, 321) = 1605
GCD(5, 321) = ( 5 x 321 ) / 1605
= 5 / 321
= 5
Step3:
LCM(1, 947) = 947
GCD(1, 947) = ( 1 x 947 ) / 947
= 1 / 947
= 1
So, Greatest Common Divisor of 685, 735, 321, 947 is 1
