Given numbers are 690, 883, 943, 155
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 883) = 609270
GCD(690, 883) = ( 690 x 883 ) / 609270
= 690 / 883
= 690
Step2:
LCM(1, 943) = 943
GCD(1, 943) = ( 1 x 943 ) / 943
= 1 / 943
= 1
Step3:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
So, Greatest Common Divisor of 690, 883, 943, 155 is 1
