Given numbers are 340, 636, 71, 668
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(340, 636) = 54060
GCD(340, 636) = ( 340 x 636 ) / 54060
= 340 / 636
= 340
Step2:
LCM(4, 71) = 284
GCD(4, 71) = ( 4 x 71 ) / 284
= 4 / 71
= 4
Step3:
LCM(1, 668) = 668
GCD(1, 668) = ( 1 x 668 ) / 668
= 1 / 668
= 1
So, Greatest Common Divisor of 340, 636, 71, 668 is 1
