Given numbers are 648, 770, 137, 162
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 770) = 249480
GCD(648, 770) = ( 648 x 770 ) / 249480
= 648 / 770
= 648
Step2:
LCM(2, 137) = 274
GCD(2, 137) = ( 2 x 137 ) / 274
= 2 / 137
= 2
Step3:
LCM(1, 162) = 162
GCD(1, 162) = ( 1 x 162 ) / 162
= 1 / 162
= 1
So, Greatest Common Divisor of 648, 770, 137, 162 is 1
