Given numbers are 602, 787, 100, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(602, 787) = 473774
GCD(602, 787) = ( 602 x 787 ) / 473774
= 602 / 787
= 602
Step2:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 602, 787, 100, 690 is 1
