Given numbers are 690, 777, 802, 148
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 777) = 178710
GCD(690, 777) = ( 690 x 777 ) / 178710
= 690 / 777
= 690
Step2:
LCM(3, 802) = 2406
GCD(3, 802) = ( 3 x 802 ) / 2406
= 3 / 802
= 3
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 690, 777, 802, 148 is 1
