GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 658) = 17766
GCD(189, 658) = ( 189 x 658 ) / 17766
= 189 / 658
= 189
Step2:
LCM(7, 715) = 5005
GCD(7, 715) = ( 7 x 715 ) / 5005
= 7 / 715
= 7
Step3:
LCM(1, 769) = 769
GCD(1, 769) = ( 1 x 769 ) / 769
= 1 / 769
= 1
So, Greatest Common Divisor of 189, 658, 715, 769 is 1
