Given numbers are 612, 988, 902, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(612, 988) = 151164
GCD(612, 988) = ( 612 x 988 ) / 151164
= 612 / 988
= 612
Step2:
LCM(4, 902) = 1804
GCD(4, 902) = ( 4 x 902 ) / 1804
= 4 / 902
= 4
Step3:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
So, Greatest Common Divisor of 612, 988, 902, 645 is 1
