Given numbers are 690, 741, 430, 898
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 741) = 170430
GCD(690, 741) = ( 690 x 741 ) / 170430
= 690 / 741
= 690
Step2:
LCM(3, 430) = 1290
GCD(3, 430) = ( 3 x 430 ) / 1290
= 3 / 430
= 3
Step3:
LCM(1, 898) = 898
GCD(1, 898) = ( 1 x 898 ) / 898
= 1 / 898
= 1
So, Greatest Common Divisor of 690, 741, 430, 898 is 1
