Given numbers are 747, 636, 814, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(747, 636) = 158364
GCD(747, 636) = ( 747 x 636 ) / 158364
= 747 / 636
= 747
Step2:
LCM(3, 814) = 2442
GCD(3, 814) = ( 3 x 814 ) / 2442
= 3 / 814
= 3
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 747, 636, 814, 685 is 1
